Simple Template Inheritance (Multiplication of two Matrices)

/* This is a simple matrix multiplication program
 * using Template inheritance.It take rows and columns of
 * two matrixes and dynamically create matrices arr1 and arr2
 * accoriding to the rows and columns user given
 * and finally add matrices arr1 and arr2 and show
