So. It turns out that the design of SurfaceFragment is a little -
shall we say - wonky.
One of the best things about ve.dm.SurfaceFragment is its magical
ability to retain the intention of its range, even as transactions
are being processed. This ability is granted by each fragment
listening to the surface's change event, and responding by using
translateRange for each transaction that gets processed. Surface
fragments also have these clever methods that allow you to get a
fragment based on another, which makes adjusting the range easy to do
inline without having to manually store multiple fragments or
modifying the original.
This sounded good, and we seemed to all be convinced it was well
designed. But if you add a console.log( 'hello' ); to the first line
of ve.dm.SurfaceFragment.prototype.onTransact, and then start using
the bold tool on various selections of text, you will find that there
may indeed be a flaw. What you will probably realize is that the
number of times that particular line of code is being called is
disturbingly large, and increases each time you do just about anything
in the editor. What's going on? How did we get here? Read on…
It turns out that fragments are immortal. We create them, they listen
to the surface's transact event, we are done with them, but the
surface keeps on emitting events to the now long forgotten about
fragments. They continue to build up over time, never go out of scope,
and bloat the hell out of our program.
The same ended up being true of toolbars - and each time the context
menu fired up a new one the old one was left in limbo, still
responding to events, still taking up memory, but not being visible to
the user.
All of this immortality was causing strange and difficult to track
down problems. This patch fixes this by introducing a destroy method.
This method unbinds events, allowing the object to finally fall out of
scope and die - and more importantly stop receiving notifications of
changes.
This is a hack, but Ed will no doubt get this situation sorted out
properly by making fragments lazy-evaluate their selections by only
storing an identifier of the most recent transaction they were based
on, see bug 47343.

Created an IndexValueStore class which can store any object and return
an integer index to its hash map.
Linear data is now stored in ve.dm.LinearData instances. Two subclasses
for element and meta data contain methods specific to those data types
(ElementLinearData and MetaLinearData).
The static methods in ve.dm.Document that inspected data at a given
offset are now instance methods of ve.dm.ElementLinearData.
AnnotationSets (which are no longer OrderedHashSets) have been moved
to /dm and also have to be instantiated with a pointer the store.

Initially just with a Wordbreak module to implement Unicode standard
on 'Default Word Boundaries'. Due to it's standaloneability this has
been written as a separate library. Non-BMP characters are currently
not supported.

isolateAndUnwrap now unwraps to a level determined by a target type
i.e. the type you are going to convert to.
Also in this commit wrap/unwrap/rewrap have been refactored to use
getLengthDifference. unwrap now takes an inner/outer unwrap depth.

rewrapAllNodes is effectively the same as unwrap then wrap
except it operates as one transaction as so avoids a potentially
invalid intermediate state.
Added some more comments for unwrapAllNodes and renamed a varaible
for consistency.
Fixed a typo in Transaction.newFromWrap comment.

wrapAllNodes was calulating the new selection incorrectly. This has
been fixed and a test added.
unwrapAllNodes takes a depth as its argument and unwraps that many
elements from inside the selection.
Tests for wrap/unwrap apply also now check that applying a wrap
and then its inverse as an unwrap result in the document reverting
to its original state.

This method will take a selection of siblings and ensure they
are the only chlidren in their first parent which can be placed anywhere
(for example the first parent of a tableCell which can be placed anywhere
is a table, and for a listItem is a list).
The method ensures no redundant empty tags are created, so if
the selection encompasses all siblings then no action is taken.
Also in this commit are two test cases run against ve.dm.example.isolationData.

-> (removed)
Differences fixed:
* Variadic arguments are like @param {Type...} [name]
instead of @param {Type} [name...]
* Convert all file headers from /** to /*! because JSDuck tries
to parse all /** blocks and fails to parse with all sorts of
errors for "Global property", "Unnamed property", and
"Duplicate property".
Find: \/\*\*([^@]+)(@copyright)
Replace: /*!$1$2
* Indented blocks are considered code examples.
A few methods had documentation with numbered lists that were
indented, which have now been updated to not be intended.
* The free-form text descriptions are parsed with Markdown,
which requires lists to be separated from paragraphs by an
empty line.
And we should use `backticks` instead of {braces} for inline
code in text paragraphs.
* Doc blocks for classes and their constructor have to be
in the correct order (@constructor, @param, @return must be
before @class, @abstract, @extends etc.)
* `@extends Class` must not have Class {wrapped}
* @throws must start with a {Type}
* @example means something else. It is used for an inline demo
iframe, not code block. For that simply indent with spaces.
* @member means something else.
Non-function properties are marked with @property, not @member.
* To create a link to a class or member, in most cases the name
is enough to create a link. E.g. Foo, Foo.bar, Foo.bar#quux,
where a hash stands for "instance member", so Foo.bar#quux,
links to Foo.bar.prototype.quux (the is not supported, as
"prototype" is considered an implementation detail, it only
indexes class name and method name).
If the magic linker doesn't work for some case, the
verbose syntax is {@link #target label}.
* @property can't have sub-properties (nested @param and @return
values are supported, only @static @property can't be nested).
We only have one case of this, which can be worked around by
moving those in a new virtual class. The code is unaltered
(only moved down so that it isn't with the scope of the main
@class block). ve.dm.TransactionProcessor.processors.
New:
* @mixins: Classes mixed into the current class.
* @event: Events that can be emitted by a class. These are also
inherited by subclasses. (+ @param, @return and @preventable).
So ve.Node#event-attach is inherited to ve.dm.BreakNode,
just like @method is.
* @singleton: Plain objects such as ve, ve.dm, ve.ce were missing
documentation causing a tree error. Documented those as a
JSDuck singleton, which they but just weren't documented yet.
NB: Members of @singleton don't need @static (if present,
triggers a compiler warning).
* @chainable: Shorthand for "@return this". We were using
"@return {classname}" which is ambiguous (returns the same
instance or another instance?), @chainable is specifically
for "@return this". Creates proper labels in the generated
HTML pages.
Removed:
* @mixin: (not to be confused with @mixins). Not supported by
JSDuck. Every class is standalone anyway. Where needed marked
them @class + @abstract instead.

The data array is now taken by reference, and the caller must perform
any copying required.
Changed tests to make a deep copy of shared data sets (mostly
ve.dm.example) before passing them to ve.dm.Document().

Also:
* Made a fragment with a null range become a null fragment
* Fixed incorrect order of arguments for binding a handler to transact event
* Added getters for surface, document and range
* Fixed several instances of passing a document instead of a surface into the constructor of a new surface fragment
* Fixed closest mode in expandRange - needed to check if parent existed before checking for it's type
* Fixed uses of ve.Transaction (doesn't exist) that were supposed to be uses of ve.dm.Transaction (does exist)
