Added a 3rd optional argument in the main method of travel depth to export the wrapper.
Add decimate() to decimate and smooth a mesh, like decimate_file().
Takes in and returns points, faces but currently outputs an interim vtk file until I figure out how to read vtkDecimatePro output.
Simplify laplace_beltrami.py.

Remove function, move function to measure.py, rename functions.

	modified:   pipeline.py
Merge branch 'master' of github.com:binarybottle/mindboggle
Comment out prep for Zernike moments call in pipeline.py
Update TravelDepthMain.cpp
sync laplace_beltrami.py
Ensure indices are always included in write_vertex_measures().
Add Brian Rossa's Python port of Arthur Mikhno's Zernike moments Matlab code.
add a checker in fem_laplacian() to ensure there are more vertices than number of eigenvalues
Fix maximum segment selection in spectrum_of_largest().
Remove output for call in pipeline.py to fill_volume_with_surface_labels().
Remove output_file input to overwrite_volume_labels() in pipeline.py
Remove intermediary vtk file outputs in decimate(). Closes #24
Remove topologically non-simple edge vertices from consideration.
Sync changes from lab.
Fix ImageMath input (remove *.vtk.nii.gz)
Add find_high_values() to find maximal value points that are not too close to one another.

This function is after find_anchors() but without directional cosines.
Revise connect_point_erosion().

Include inner as well as outer anchor points (inners are removed if they result in endpoints).
Replace likelihood map with a simple product of the normalized travel depth and (new) mean curvature maps.
Add incremental output vtk files for debugging.
Add segmentation at each iteration, and remove a fraction of the lowest values per segment.
Test for simple topology ignores the second output of topo_test().
