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.

instead of testing if an operator starts
with the letter \o we keep an explicit
dictonary of operators which should
be rendered using mover instead of
msub.

In TeX display math mode \sum_a^b is rendered as
munderover, however \alpha_a^b is redndered as
msubsup.
This changes improves the heuristics to differentiate
between munderover operators such as sum prod and
other macros such as alpha, beta ...

When rendering subscripts font arguments such as upright
font were not passed to the child nodes.
This changes passes the parameters.
