Title: Enh/mrtrix

This branch contains wrappers for all of the useful MRtrix (http://www.brain.org.au/software/mrtrix/) functions as well as a MATLAB interface for converting tracks stored in .tck to TrackVis .trk files. It also contains the most recent updates to the CMTK nodes adapted from the ConnectomeMapper (https://github.com/LTS5/cmp).

There are now single-subject and group level workflows for Camino and MRtrix-based connectivity processing. Tutorials demonstrate both single-subject and group-level connectome mapping using constrained spherical deconvolution to resolve crossing fibers and then generating the tracts probabilistically The structural segmentation is pulled from Freesurfer and parcellated into the high-resolution 1015-node atlas in order build the structural connectome. In addition, network statistics are calculated using NetworkX and these networks are output for both MATLAB (.mat) and the ConnectomeViewer (.cff).
