## Write a short comment describing this function
# The first function, makeCacheMatrix creates a special "matrix",
# which is really a list containing a function to
# 
# set the value of the matrix
# get the value of the matrix
# set the value of the inverse matrix
# get the value of the inverse matrix

makeCacheMatrix <- function(x = matrix()) {
    m <- NULL
    set <- function(y) {
        x <<- y
        m <<- NULL
    }
    get <- function() x
    setinverse <- function(solve) m <<- solve
    getinverse <- function() m
    list(set = set, get = get,
         setinverse = setinverse,
         getinverse = getinverse)    
}


## Write a short comment describing this function
# Calculates the inverse of the special "matrix" created with the
# above function. However, it first checks to see if the inverse has 
# already been calculated. If so, it gets the inverse from the cache
# and skips the computation. Otherwise, it calculates the inverse of
# the data and sets the value of the inverse in the cache via the
# setinverse function.

cacheSolve <- function(x, ...) {
        ## Return a matrix that is the inverse of 'x'
    m <- x$getinverse()
    if(!is.null(m)) {
        message("getting cached data")
        return(m)
    }
    data <- x$get()
    m <- solve(data, ...)
    x$setinverse(m)
    m
