Description
A method to obtain the underlying matrix as element of the corresponding full matrix space analog to the similar method of MatrixGroupElement_generic should be added. This may be a shortcut for the following:
sage: LM = lie_algebras.sp(QQ, 4, representation='matrix') sage: e1, e2, f1, f2, h1, h2 = LM.gens() sage: mh1 = LM.associative_algebra()(dict(h1)); mh1 [ 1 0 0 0] [ 0 -1 0 0] [ 0 0 -1 0] [ 0 0 0 1] sage: mh1.parent() Full MatrixSpace of 4 by 4 sparse matrices over Rational Field

I made a few small fixes to the documentation and added another test. If my changes look good, then you can set a positive review.
