When creating free and finitely presented groups, default variable names
are often ugly.
{{{
sage: F = FreeGroup(12)
sage: F
Free Group on generators {x0, x1, x2, x3, x4, x5, x6, x7, x8, x9, x10,
x11}
sage: F/[F([1,2,2,1,1,4,7,-8]),F([10,10,4,-5,4,-8]) ]
Finitely presented group < x0, x1, x2, x3, x4, x5, x6, x7, x8, x9, x10,
x11 | x0*x1^2*x0^2*x3*x6*x7^-1, x9^2*x3*x4^-1*x3*x7^-1 >
}}}
Created by a utility function, the simple generator in this patch provides
an easy way to consistently generate better variable names, and will be
useful in creating free groups algorithmically.
