N-Spin System Simulator (NSSS) for NMR

This is NSSS version 0.1.0, a N-Spin System Simulator (NSSS) for NMR that is fully based on the Cartesian Operator Product Formalism.

This software was initially written (in 1994) because Ray Freeman asked me if I could check his cartesian operator product calculation for the DEPT sequence.

My second intention was to write some code for a virtual spectrometer, something I never did.

NSSS is a C API. The user has to write a C program to use it. Demo executable programs named dept and abc1d can be built from the distribution file. They provide examples of NSSS use.
