* Finished Model and Controller for now, with a lot of changes.
* There is a bug that the first image is not renderd. So only rendering
exists after movement.
update the project files

create cScene and cDataset as shown in the structure overview
refs #65 using correct name "passThrough" for the shader
enable the open dialog, for now only be able to load 256x256x128 grid

loading the raw dataset generates a aabbx as vbo
add render possibility of the aabbx
add fullscreen mode
get glew including problem
fixed fullscreen, fixed glew import
fixed rendering of the aabbx
* static linking glew for windows
* _moved camera flag disabled, causes flickering in some cases
uploading the necessary files for the static linking
starting to outsource the shader usage to useShaderProgram inside the
cShaderHandler
bugfix rendering
restructured rendering method in cCamera
minimize connect statement
ref #64 using again _moved flag of the camera, without the flickering.
Problem was that the buffer swapping was applied also with no rendering.
