Reset mathcal fonts to default

[psivesely]

mathptmx introduces a really terrible font for mathcal. Consider adding \DeclareMathAlphabet{\mathcal}{OMS}{cmsy}{m}{n} to reset it to the standard alphabet.

I see what you mean. It's a little calligraphically OTT.

With just mathptmx:

With the reset:

So, I think the proposed command sets the "alphabet" for \mathcal for the OMS encoding block, to the cmsy font, m series (medium, I think), n weight, which is the ordinary default.

This should be safe to add to the class file, I think.
