Title: Doctest Coverage for Integral module

Doctest Coverage for Integral module

Improved the Doctest Coverage for Integral module. Several functions which are defined within other functions are not covered with doctests.

The functions not covered are:
integrals\integrals.py calc_limit(a, h)
integrals\risch.py sort_key(arg)
integrals\risch.py substitute(expr)
integrals\risch.py derivation(h)
integrals\risch.py deflation(p)
integrals\risch.py splitter(p)
integrals\risch.py exponent(g)
integrals\risch.py integrate(field=None)
