cachematrix.R

## This script contains a set of functions that handles a matrix
## and its inverse caching them to avoid high time-consuming
## computation.

## This function "prepares" the cache-matrix object to be
## handled in a cached way from an input matrix. Enables four
## functions (2 setters and two getters) to handle the cached
## matrix and its inverse.
