This patch does the following:
* reimplements class
{{{sage.modular.arithgroup.arithgroup_element.ArithmeticSubgroupElement}}}
as a Cython extension type, resulting in considerable speed gains;
* modifies element constructor methods for the classes in
{{{sage.modular.arithgroup}}} for consistency with the category framework;
* various small changes (mostly to {{{__cmp__}}}) that make !TestSuite
doctests pass for all these classes.
The patch adds no new methods, but speeds up arithmetic with elements of
SL2Z and its subgroups by a factor of about 4 on my machine.
