Preparing the Interface for integration with the ContourTree module.
Added a method to save the multidimensional transfer functions generated by the ContourTree module to disk.
Added the branch map and data size as parameters for the simplification function. The vertices of simplified branches are now reassigned to their parents.
Added both min/max scalar value fields to the feature set. These fields will store the minimum and maximum scalar values of the branch vertices respectively.
Added some function calls to newly defined functions.
Fixed the calc_final_alpha function to reflect todays discussion with co-advisor. Added the seeking of both maximum and minimum scalar values of a branch on the calc_branch_feeatures function. Copied the function to save the vertex to branch map from main.cpp to ctfunc.cpp.
Added a class to represent the multidimensional volume data that inherits VolumeData class. Loads a dummy volume to test it.
Changed some minor things on the shader.
Addition of the multidimensional volume class to the project files.
Resized the Visualizer window to fit smaller screens. Added a loading call for the multidimvolume class
Merge branch 'multidimtf'
Writting the load* functions that handle de loading of the opacity and color transfer functions and the vertex-to-branch volume.
Written a function to clamp the values of the opacity between 0 and 1.
Removed some commented code and the test fucntion call from the Renderer class. Created a file test.cpp to test the loading of the datasets.
