New description:
The current implementation of orthogonal polynomials is just a wrapper
around maxima. (see http://wiki.sagemath.org/symbolics/)
This update holds the following changes:
* using of the pynac class for symbolic functions.
* faster evaluation in general
* evaluation of special values
* mpmath for numeric evaluation
'''Remarks:'''
* The current patch needs scipy-0.8. One has to install it before
testing (see #9808 for spkg's and installation instructions)
* Some of the old doctests in the old file don't work any more, due to
coercion problems with pynac (see #9769)
* Some doctests in Sage change, due to the fact that new BuiltIn
functions are added. symbolic.random_test.py had output changes since the
random expression creation changed of course. The tests in pynac.pyx also
changed, but this has a strange behavior (see below).

Comment (by tscrim):
** Here is a review patch which does a bunch of documentation formatting
tweaks. There are probably one or two other things that will need to be
addressed, but I'd like to get the ball rolling on this again (and I need
some sleep right now).
Best,[[BR]]
