First implementation of 2D Cartesian space.

Browse source 
Files and types with 'Cyl' have been changed to '2DCyl' to better
differentiate between the two types of 2D geometry.

Solvers for charged and neutral particles in 2D Cartesian space.

Added solveds for 1D neutral particles (this branch is not the place to
    do it, but it was a minor change).

User Manual updated with the new accepted options.

When a 2D cylindrical geometry is used ($z$, $r$), a Boris solver\cite{boris1970relativistic} is used to move particles accounting for the effect of the symmetry axis.
This pusher removes the issue with particles going to infinite velocity when $r \rightarrow 0$ by pushing the particles in Cartesian space and then converting it to $r-z$ geometry.
Velocity in the $\theta$ direction is updated for collision processes, although the dynamic in the angular direction is assumed as symmetric.
Cross-sections are read from files.
These files contains two columns: one for the relative energy (in $\unit{eV}$) and another one for the cross-section (in $\unit{m^{-2}}$).
