One of the easiest dimension formulas is for the dimension of
{{{S_2(Gamma(p))}}}. However, in Sage, computing this dimension is
shockingly slow. For example,
{{{
sage: time Gamma(7).dimension_cusp_forms()
3
Time: CPU 17.27 s, Wall: 17.30 s
sage: time dimension_cusp_forms(Gamma(7),2)
3
Time: CPU 17.22 s, Wall: 17.25 s
}}}
Fix this.
