NAME: @code{space} -- piecewise polynomial finite element space
@clindex space
DESCRIPTION:
@noindent
The @code{space} class contains some numbering 
for unknowns and blocked degrees of freedoms
related to a given mesh and polynomial approximation.
SYNOPSIS:
@example
    space Q (omega, "P1");
    space V (omega, "P2", "vector");
    space T (omega, "P1d", "tensor");
@end example
PRODUCT:
@example
    space X = T*V*Q;
    space Q2 = pow(Q,2);
@end example
