Caching the Inverse of a Matrix:
Write the following functions:
1. makeCacheMatrix: This function creates a special "matrix" object that
can cache its inverse.
2. cacheSolve: This function computes the inverse of the special
"matrix" returned by makeCacheMatrix above. If the inverse has already
been calculated (and the matrix has not changed), then the cachesolve
should retrieve the inverse from the cache.
