Closes #60

implements computation of invariant from a sigmak, cos_theta_ij pair.

Function of computing sigmaj given sigmak and theta_ij is here in julia https://github.com/mmikhasenko/ThreeBodyDecays.jl/blob/88a8674b37e646479bcf4e838a70cd027ebb958b/src/kinematics.jl#L19-L29

The model computes value that is non nan, now.
