## This file contains functions which allow for the caching of the inverse of
## a matrix.
## A function that creates a special "matrix", which is a list containing
## functions to set the value of the matrix, get the value of the matrix,
## set the inverse of the matrix, and get the inverse of the matrix.

## A function that calculates the inverse of a special "matrix of the type
## created with the above function. First checks to see if the inverse has already
## been calculated and if so, returns a cached version of the inverse.
