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).
