Added the function loadRawFile that loads a RAW file directly. This is meant to
diminish code replication on the data loading methods of the ResourceManager class.
Added the methods to load a vertex to branch map as a 3D texture (previous commit) and
load a multidimensional transfer function as a 2D texture. These will be used to
render the results of the opacity flow on the branch decomposition of the ContouTree
module. New shaders must be created to render the results appropriately. The existing
shaders will be kept the same for backwards compatibility.
Merge branch 'multidimtf' of https://github.com/schardong/Visualizer into multidimtf
Removed some Qt creator project files that were included on the last push accidentaly. Small typo on the last commit message "They will be used to render the results of the opacity flow on the branch decomposition of the ContouTree module".
