Packaging and Improvements in Visualizers

• Add Structural Connectivity and Pearson Correlation Edge Bundle Viewers (circular viewers)
• Replace MPLH5 Visualizers(PSE Continous, Wavelet, Fourier, Topographic, Pearson, Complex Coherence) with new ones based on D3.JS
• Packages distributed with Pypi (tvb-library and tvb-framework)
• Bug Fixes
