Make sure ripples code have same output.

For now we will keep bz_FindRipples and detetec_swr as separated functions but will change the later so the inputs/outpus are the same. Plus add some new functionalities to both functions

Sounds good to me.

@eliezyer also wanted to be involved in this and a few other issues, but I'm having trouble assigning him so I'll just tag him here
