[Numpy-discussion] Moving docstrings from C to Python

I started to do the same with array methods, but before I spend too much
time on it, I'd like to be sure I'm doing the right thing.

1. In add_newdocs.py, add
from numpy.core import ndarray

2. then add an entry for each method, eg
add_docstring(ndarray.var,
    """a.var(axis=None, dtype=None)
    Return the variance, a measure of the spread of a distribution.

    The variance is the average of the squared deviations from the mean,
    i.e. var = mean((x - x.mean())**2).

    See also: std
    """)

3. in arraymethods.c,
delete static char doc_var[] = ...

remove doc_var in
{"var", (PyCFunction)array_variance,
     METH_VARARGS|METH_KEYWORDS, doc_var},
