The Lapack class

INTRODUCTION
	LAPACK	is  written  in  Fortran 90 and provides routines for solving systems of simultaneous linear equations, least-squares solutions of
       linear systems of equations, eigenvalue problems, and singular value problems. This extension wraps the LAPACKE C bindings to allow  access
       to  several  processes  exposed	by  the library. Most functions work with arrays of arrays, representing rectangular matrices in row major
       order - so a two by two matrix [1 2; 3 4] would be array(array(1, 2), array(3, 4)).

       All of the functions are called statically, for example $eig = Lapack::eigenvalues($a);
