// Recall that a Hill cipher has as a key a pair (A,v) where A is a nxn invertible 
// matrix over some field F_p and v is a n-dimensional vector. The message space 
// is F_p. To encrypt a message m, we send it to Am + v. To decrypt enciphered 
// text c, we evaluate A^{-1}(c - v) where A^{-1} is the inverse to the matrix A. 

// We import a very basic linear algebra library from a subfolder.
