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.

When collecting user feedback regarding the native
rendering option on the German Wikipedia (T346795)
it became apparent that some power users aim for bigger
and bolder fonts and a more LaTeX-like layout.
MathML, however, aims to format math as an integral part
of the text with uniform fonts and spacing.
To match both user needs, this patch adds a new rendering
option that uses client-side MathJax (without a need for
restbase or mathoid).
* Adjust MathJax`s loader to be compatible with the mw loader
* Add new rendering mode
* Copy MathJax source to resource module as foreign repo

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.

This change makes the availability of the Wikibase

* to named functions and named operators
* You can consider using that invisible apply character (U+2061) after other function names with known arguments (such as \sin, \cos...). Some accessibility tools take advantage of it, I am told, but it may also be used to provide correct spacing from the MathML operator dictionary. In Chrome <mi>sin</mi><mi>a</mi> will show up with no added spacing as sina, which is not ideal.
* namedFct with any succeeding macros/characters have an apply function
