Declaring math versions

\DeclareMathVersion {<version>}

Defines <version> to be a math version.

If used on an already existing version, an information message is written to the transcript file and all previous \SetSymbolFont or \SetMathAlphabet declarations for this version are overwritten by the math alphabet and symbol font defaults, i.e. one ends up with a virgin math version.
