Chains of single letter mi elements are rendered with no
space but one mi element with multiple letters gets
space. For example, the operator log will be translated
to <mi>log</mi> rather than <mi>l</mi><mi>o</mi><mi>g</mi>
as done by wikitexvc.
* Squash literals into single element, iff they don't
contain commands
Following the implementation of the literal rendering
it seems that all literals with special behaviour have
a command.

* Reapply the logic of \log rendering to \operatorname
* Deduplicate applyFunctionDetection
Note this still does not solve the rendering problem for
operator names with more than one letter as these generate
mrow elements with single letters. Those are not rendered
with space in FF.

In LaTeX line breaks in matrix elements
have an optional argument that controls
the vertical spacing between the current
and the next line. For example,
{\begin{aligned}a\\[6pt] b\end{aligned}}
generates a 6pt space.
This was never implemented and ignored by
mathoid.
The native MathML implementation is unaware
of the optional argument and just prints it
to the next line.
* This commit ignores the input on the grammar
side.

As indicated in the comment the code intents
to add "additional italic mathvariant
when bold already". However, effectively it
always added an additional -italic when
any mathvariant was given.
* Only add '-italic' if mathvariant is 'bold'

Instead of manually crafted $this->testCase properties.
Also make use of the dedicated PHPUnit feature to mark as test as
passed. While assertTrue( true ) is a very common hack it can be
confusing.

Add doc-typehints to class properties found by the PropertyDocumentation
sniff to improve the documentation and to remove the exclusion of the
sniff.
The activated sniff avoids that new code is missing doc-typehints or
real-typehints.

Just removing unused code that never did anything. Note this is only
in a test. As long as all tests still succeed this can't really cause
any problems, I believe.

In MathML outer table boarders are represented with the
notation attribute of an menclose element. The inner
boarders are represented by the rowlines attribute
of the mtable element. The rowline element accepts
a space seperated list of row boarders. In LaTeX
the bottom line is represented by a new matrix row
that only contains \hline.
This change discover \hline elements in matrix cells
and then determines if it is in the first or last line.
When it is in the last line, the line is removed to avoid
an empty <mtr /> in the output.

Originally the parse tree was a binary tree, from that
time matrix element were put into that data structure.
This was partially undone, but not full which leads to some artifacts
in matrix cells.
One of the problem is that due to the binary parse
tree structure the postprocessing did not correctly
identfy \limits.
This change changes reduces nesting from matrix, and regards
matrix instances as two-dimensional TexArrays.

TexArray is an array of tex nodes. To improve
readability and type hinting we make TexArray
iterable.

To reduce the complexity of the parse tree we remove the curly
element which is used for grouping in TeX. Instead, we use
use an attribute which defines if the group is put into curly
brackets or not. The functionality of the curly element
is transferred to the TexArray which was the only possible
child of the curly element before. To ease the transition,
we add a special constructor to TexArray.
We could not measure any performance implications of this change.
