* Default to NumPy for simrank_similarity

* fix typo: targete -> target

* arg G left out of call to simrank_similarity

* Fix

* More

* Add pre/post processing of nodes in simrank_similarity

Added test for noninteger nodes
Added and updted examples in docstrings
cleaned up some tests

* parametrize tests so new _python version tested

* Move similarity_numpy code to private function

so deprecating requires very little code change.

* implement changes from the discussion

Move warning so doesn't show unless _numpy() version called
Add test of difference between python and numpy version
Add exception when methods don't converge
Add tests of convergence exception
