* Tokens are now immutable. The progress of transformations is tracked on
chunks instead of tokens. Tokenizer output is cached and can be directly
returned without a need for cloning. Transforms are required to clone or
newly create tokens they are modifying.
* Expansions per chunk are now shared between equivalent frames via a cache
stored on the chunk itself. Equivalence of frames is not yet ideal though,
as right now a hash tree of *unexpanded* arguments is used. This should be
switched to a hash of the fully expanded local parameters instead.
* There is now a vastly improved maybeSyncReturn wrapper for async transforms
that either forwards processing to the iterative transformTokens if the
current transform is still ongoing, or manages a recursive transformation if
needed.
* Parameters for parser functions are now wrapped in abstract Params and
ParserValue objects, which support some handy on-demand *value* expansions.
Keys are always expanded. Parser functions are converted to use these
interfaces, and now properly expand their values in the correct frame.
Making this expansion lazier is certainly possible, but would complicate
transformTokens and other token-handling machinery. Need to investigate if
it would really be worth it. Dead branch elimination is certainly a bigger
win overall.
* Complex recursive asynchronous expansions should now be closer to correct
for both the iterative (transformTokens) and recursive (maybeSyncReturn
after transformTokens has returned) code paths.
* Performance degraded slightly. There are no micro-optimizations done yet
and the shared expansion cache still has a low hit rate. The progress
tracking on chunks is not yet perfect, so there are likely a lot of unneeded
re-expansions that can be easily eliminated. There is also more debug
tracing right now. Obama currently expands in 54 seconds on my laptop.

By first summarizing a node tree or node selection and then using the normal deepEqual function we are able to take advantage of native QUnit functionality to make diagnosing a problem easier under failing conditions and reduce the verbosity of the output under passing conditions.

* Make nodeSelectionEqual() accept a desc parameter and use it for
building descriptions
* Put the array element number in the desciption too
* Add descriptions for selectNodes tests and pass them through
Change-Id: Icd2894d11516234598cbd984cc8d88f705bfc1d6
* Don't crash if b.children has a different length than expected
* Don't crash if b.children is absent but expected
* Check if b.children is present when it's not expected
* Add assertion when neither a.children not b.children are present; this
makes the number of assertions for leaves equal to the number of
assertions for branches
* Check attributes too
* Accept a desc parameter, and add node paths (like
list/listItem/paragraph/text) to the descriptions
* Use desc parameter for all calls (some tests were already using it,
even though it didn't actually exist)

This means inserting things like </p><p> are now synced correctly and
split the paragraph in the model tree. Merges (removing e.g. </p><p>)
aren't supported yet.
Also, this needs tests, Trevor tells me he's working on porting replace
tests from the old ve/ directory

The tree sync for content replacements was adjusting the parent of the
text node affected, rather than the text node itself. This was because
it called getNodeFromOffset(), which returns branch nodes. Switched it
to use selectNodes() in leaves mode

This was because the while loop was never entered as end >= left was
true from the start. Convert the while loop to a do-while loop to make
sure it runs at least once

Now returning an empty array when a non annotated character is found
in the range. No longer looping through each annotation, simply
comparing to previous characters annotations and trimming differences.
Write additional test.
