Implementations for CLEO

Implementation of the (pipi)-s wave using K-matrix formalism (pwprotected)
Writeup of the method used for implementations below.
The code for a C++ implementation of a 2x2 matrix can be found in ~urner/pwa/pipis/pipis.cc, pipis.h, Makefile (pwprotected)
Mathematica implementation of 2x2 K-matrix for (pipi)-s wave (pwprotected)
Mathematica implementation of 3x3 K-matrix for (pipi)-s wave (pwprotected)
The 2x2 K-matrix parametrization was taken from High-statistics study of f_0(1500) decay into 2pi0
