A print function that pretty prints sympy Basic objects.
Once the extension is loaded, Sympy Basic objects are automatically pretty-printed.
As of SymPy 0.7.2, maintenance of this extension has moved to SymPy under sympy.interactive.ipythonprinting, any modifications to account for changes to SymPy should be submitted to SymPy rather than changed here. This module is maintained here for backwards compatablitiy with old SymPy versions.
