Double-precision column-major matrix for use with LAPACK.
Your code can have huge performance hits if you fail to realize this is column major. For datasets, your columns should be individual points and your rows should be features.
TODO: If it's not entirely obvious or well documented how to use this class please let the FASTlib people know.
