[Felix-language] mathmode

[john s. <sk...@us...>]

I'm changing the display rules for mathmode.

First, { } will not be displayed in mathmode.
Use \{ \} if you want to see something.

Second, a Felix identifier will usually emit

	\mathtt{identifier}

which will cause it to be typeset in teletype font, similar to the usual
program text font I hope.

Next, I am thinking instead of the above, if you specify a font operator:

	\mathcal { ... }

that overrides \mathtt. In fact I think a stack of fonts will be maintained.

Fourth, i think I will make a single character identifier an exception
and typeset that using \mathit.

This means \mathit and \mathtt probably should NOT be used as operators!

In general formulae like

	\mathcal X
	\mathcal {x + y}
	\mathcal (x + y)

etc affect typesetting and are ALSO Felix functions. So take care
to use these functions in a way that the font change make it
clear that an operation is performed, and what it is performed ON.
