Fixing the seed of random number generator in MC simulation

[ImanKafian]

Hi,

I am running a MC simulation to estimate the reflectance and transmittance from a 3D slab with low number of photons (100K). I would like to know how I can fix the seed value of the random number generator in MC object to simulate exactly the same reflectance and transmittance whenever I perform the MC simulation.

Thanks.

Set the value of the "rnginit" parameter in the Mc constructor to a fixed unsigned integer value/seed.
