Traversal in and tested. Next step is to remove references to old code
Removed reference from spectral_clustering to old csgraph
csgraph updated from hierarchical.py
Removed actual _csgraph file, tests still all pass
Turns out sparsetools wasn't needed either
Missed a spot
Reference to graph components updated in dev docs
Two more spots. I think that's it
Now that the folder has more than just mst in it, rename to sparsetools, which should help with referencing it.
directed=False to ensure the connected components are accurate
Turns out test_traversal doesn't contain any tests for connected_components. Removed the unneeded tests, will create a test for connected_components after this passes Travis
Fixed import statement
Test for connected components and pep8 for tests
Merge branch 'components' of github.com:robertlayton/scikit-learn into components
