New description:

 Implementation for the wrapping of GAP's {{{DirectProduct}}} function for
 finitely presented groups.
 {{{
 sage: G = FreeGroup()
 sage: C3 = G / [G([1,1,1])]
 sage: C3.direct_product(C3)
 Finitely presented group < a, b | a^3, b^3, a^-1*b^-1*a*b >
 }}}
 My approach is object oriented as a {{{FinitelyPresentedGroup}}} method,
 as opposed to a function call such as {{{direct_product_fpgroups}}} taking
 a list of groups as input.
 Depends on #14790 for variable names.

 __Apply__
