Documentation for flattenRing doesn't fully describe functionality

Indeed, several of the methods for flattenRing are currently undocumented. Will be fixed shortly.

Documentation for flattenRing doesn't fully describe functionality

Rewrote this documentation to include things like Galois fields and rings declared as fields. I was extremely confused by the description of the Result option. I changed the page to...

GF command sets the symbol "a" to a random element of the field

The function GF creates an explicit description of the field by defining the polynomial ring ZZ/p[a], then taking the quotient by an irreducible polynomial of the right degree. You can...

GF command sets the symbol "a" to a random element of the field

Okay, I just actually tried this and it is definitely a problem beyond just needing to be documented. GF overwrites "a" even if it's already defined!

GF command sets the symbol "a" to a random element of the field

It seems there are two possible philosophies here: 1. Make "a" like the "T" in a Hilbert series---used to construct and represent something algebraic, but not exposed to the user...
