+/*    
+1.6.4.0    30/10/2011
+           -->> MATRIX_H
+            *  Eliminated namespace std; already included in mbed.h
+            *  Operator Overloaded (). For assignment and getValue.
+            *  Almost all operators declared as friend functions.
+
+            -->> MATRIXMATH_H
+            *  Added Function Eye(). Creates an identity Matrix of specified dimensions.
+            *  Added Function dotProduct(). to find the dot product of two vectors.
+               -->> You need to pass two Vector Matrices of any dimmensions.
+                    They could be in the form: A( 1,n ) B( 1,n )
+                                               A( n,1 ) B( 1,n )
+                                               A( n,1 ) B( n,1 )
+                                               A( 1,n ) B( n,1 )
+                    As long as have same 'depth' and are vectors, the dot product.
+                    will be returned.
+
+            -->> MATRIXMATH_Kinematics.cpp
+            *  Created file MatrixMath_Kinematics.cpp To Hold the definitions of
+               kinematic operations.
+
+            *  Define Functions RotX, RotY, RotZ, Transl. for Matrix Transformation
+               operations.
