Comment (by benjaminfjones):
Yet more work in progress, added lots of doctests, in particular to show
that problems in #4230 and #3426 are fixed by this patch. One feature this
patch adds is the ability to solve
Bessel's diffeq (using Maxima) and get a usable symbolic solution back
(see the doctests in the module level docstring and in the Bessel()
function).
Added brief mathematical exposition on the module docstring as well as
some usage EXAMPLES.
I think the patch is more or less ready for initial review. All tests
withing the new file `sage/functions/bessel.py` pass on my machine and
sage-5.6.beta3, but there are several doctests failing in other places
that reference the Bessel functions. I'll work on patching those up for
the next iteration.
