Volumetric Time series visualizer for TVB and updating other visualization

by Robert Parcus for International Neuroinformatics Coordinating Facility

The main goal of this proposal is to implement a time-series visualizer for 4D data in TVB, which would enable users to work with their functional MRI data directly from the browser. Then I will work on rewriting some of the visualizers that are currently implemented using MatplotLib and MPLH5, backed with web-friendly tools.
