$\left(a\right)'$ produced rendered MathML output that
looked like $\left(a'\right)'$.
* Remove the deriv (') state when rendering the element
within the brackets.

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.

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.
