MathML internals - embellished operators, getBase() accessor functions

MathML internals - embellished operators, getBase() accessor functions
https://bugs.webkit.org/show_bug.cgi?id=78617

Patch by David Barton <dbarton@mathscribe.com> on 2012-02-17
Reviewed by Eric Seidel.

Define functions that return an unembellished "base", by omitting
subscripts/superscripts, underscripts/overscripts, or denominators. This is needed in
subsequent patches both for correct operator stretching and simple code factoring.

No new tests.
