mathtex lacks \binom support #12

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?

\binom{a}{b} is loosely equivalent to \left(\frac{a}{b}\right) with no
fraction beam.

mathtex doesn't currently support this.

It may be worth following the lead of TeX and adding support for \genfrac,
upon which \binom, \frac and others can be based.

A related function is \stackrel, which can also be based on \genfrac.

Patch attached that adds genfrac, binom and stackrel, with frac refactored to 
use
genfrac.

It is getting late here, but I'll review it properly in the morning. Thanks!

Committed along with the appropriate test-cases in r90.
