1. Set the number of the initial particles in 1 run (1 for e- and 3e6 for gamma) (done)

NOTE: should we use gamma or opticalphoton? Whether it possible to use opticalphoton as a thrown particle?

2. Set the particle type (e- or gamma), position, momentum and momentum direction (done)

NOTE: are these parameters correct? (should we set them only?) Study if it possible to throw photon from outside the slab.

3. Distribute the thrown optical photons in time according to the laser pulse shape.

4. Change the parameters above without compiling (with the help of .mac file or command line option). Needs to be done from scratch
