Added method check_bone_index in SkeletonFitting that checks if the bones indeces
given a method correspond to the skeleton.
Enable back color shading
Reactivation of code that allows to see colour by camera and colour mapping.
Added typed for std::vector<boost::shared_ptr<RGBD_Camera> >
Fixed seg faults and other errors when there is no info on the frames.
Errors occur mainly in SkeletonFitting.
Added point selector for origin set up in MulticamViewer
Added CameraCalibrator class. This class takes the points given from
MultiCamViewer and recalibrates the central camera
Substituted several method(void) for method()
Improved calibration code to work using the previous T matrix of the camera
Fixed precision problems when reading and saving calibration files.
Improved CameraCalibrator to work with all the cameras.
Changed pre multiplication to post multiplication on CameraCalibrator.
Pre-multiplication was giving wrong matrices.
Simplified RGBDCamera boundingbox code, also improved code to calculate
global coordinates. Background segmentation is now controlled by a variable.
IMPORTANT RBGDCamera now discards first 30 frames and last 57 frames
Camera calibrator now also calibrates the rotation.
