* First version of automated colour based boundary conditions for OpenCascade geometry

Browse Source 
* Modified the menustat.tcl file to add an entry in the "Special" menu for the colour based boundary properties functionality
* Added the relevant TCL wrapper functions in ngpkg.cpp to enable the above functionality
* Note: The core functionality is implemented in the file "occauxfunctions.cpp"
