Class Summary

Defs	Wrapper class for common definitions.
MatrixInversion	This class is responsible for inverting a matrix for solving a linear equation Ax = b . This is needed for finding the physical coordinates from screen coordinates (for example, in showing mouse coordinates on the viewer in real time). Here we need to solve the following equation for X_physical X_physical * Transformation_Matrix = X_screen We know the screen coordinates (current mouse coordinates), but need the corresponding physical coodinates. This is a singleton class.
SessionMgr	Session manager class.
StringWrapper	Wrapper class for passing and receiving string values from functions.
