Documentation adapted to the new way to define geometry and pushers.

Examples are currently being tested and small modifications are being
done to include a reference output.

Example of 0D geometry.
Mostly used to test collision processes.
This example includes Ar and Ar+ with self-collisions for Ar and elastic collisions for AR-Ar+.
Different starting temperatures for each species that end up in equilibrium.
The gnuplpot script 'plot_Temperature.gp' generates a plot of the species temperatures.
The result is provided in the output folder to compare if modifications to the code are made.

This case is useful to explain how fpakc can work with different geometries (Cartisian and Radial in this case) using very similar input files and the same mesh.
From the position to the left, electrons are emitted at a constant rate.
The electric potential at the left is fixed at 0.
Depending on the geometry (which affects the symmetry) different distributions of the electron density and electric potential are achieved.
The last iteration obtained for these cases is in the output folder.
