Description :
A function of a (single) particle energy and angle COSINE (to surface normal).
The first argument of the function of 2 scalars (compute(E, cosTheta)
is the energy E, the second the COSINE of the angle (to the normal).
The function of 5 scalars (compute(E, cosTheta, )
is the same function with extra parameters, hence its five arguments are:
1- the energy E,
2- the COSINE of the angle (to the normal),
3- the material model Id of that surface (an integer stored as a float)
4- the material Id of the impinged surface (an integer stored as a float)
5- the particle type Id (an integer stored as a float)
whereas the parameters arguments 3, 4 and 5 could be used with a different
meaning (this meaning is used by the material properties functions used
for secondary emission, etc.).
The function of 1 and 4 scalars return
angle-averaged values for isotropic distributions ( * sin(theta) * cos(theta) * 2
for solid angle and Labertian law factors for a surface in 3D).
These isotropic versions are numerically computed in this class, but should
rather be given analytically in derived classes when possible (override!)
