🎉 Feature request

Is your feature request related to a problem? Please describe.

The ray tracer should receive the RNIP and BETA parameters in order to determine CRE traveltime curve. From NIP point, two reflection rays are traced with angle TETA in relation to the normal determined by the normal ray that reaches NIP. Both rays should reach the acquisition surface.

After that, CMP and Offset coordinates are calculated and the time misfit is given by the difference between the CRE traveltime calculated and the sum of the traveltimes between these two reflection rays.

Describe the solution you'd like
A clear and concise description of what you want to happen.

Scratch of stereotomography algorithm #17
99279e5 
The program sfstereoniptomo uses the NIP sources to trace rays
from them to acquisition surface in order to obtain the traveltime
curve and to compare it with the CRE traveltime calculated values.
The data misfit will be used to update the velocity model.

We also add the program sfgetparameter to extract the parameters from
parameters cube for (t0,m0) location given

Plot NIP sources and m0s #17
bdace3c 
Utility python script to plot the NIP sources using depth coordinates
and to plot m0s in the acquisition surface. To setup input files run
'scons -f SConscript2' and after run the viewNipSources.py script. It
will load generated files and plot sources using matplotlib python
library
