## Write a short comment describing this function
## This fuction calculates the inverse of a matrix
## If the inverse is calculated already "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 set_inverse function.
