#11746: Unify the definition of "monomial", introduce "term"
-----------------------------------+----------------------------------------
Reporter: boothby | Owner: boothby
Type: defect | Status: new

Consider:
{{{
sage: R.<x> = QQ[]
sage: S.<u,v> = QQ[]
sage: f = 2*x
sage: g = 2*u
sage: f.is_monomial()
True
sage: g.is_monomial()
False
}}}
According to Wikipedia, there are two conventions on the matter, and we
should support both. I propose that we accept neither {{{f}}} nor {{{g}}}
as monomials, and add the method {{{is_term}}}:
{{{
sage: f.is_monomial()
False
sage: g.is_monomial()
False
sage: f.is_term()
True
sage: g.is_term()
True
}}}
