Reorganize lapack and add more routine types

[EricaCMitchell]

Description and Details

Adds the s, c, d, and z types of LAPACK routines to clapack_fortran.h

• Some routines had a comment above them explaining what they did and others didn't. To be consistent, all routines that are similar have the d type subroutine and its purpose commented in.

lapack.cc seems to contain three different sections: 1) wrappers, 2) madness functions, and 3) template instantiations.

• The wrappers have been reorganized to be in the order of clapack_fortran.h to make it more readable.
• The wrappers themself have been renamed without the d type in the wrapper name to avoid confusion in the madness functions as to why the d subroutines are being used in functions that accept various tensor types.
• The template instantiations have been reorganized so that those of the same madness function are next to each other that way you can read what types are available easier.
• Most madness functions have been instantiated with double and double_complex. In particular, I needed a complex version of inverse.

Given that the templates have to be instantiated with modern C++ compilers, would it make sense to move the test parts in lapack.cc to its own file?
