Dynamic schedule for collision loop to balance the uneven number of
...
collisions in each cell.
No success with balancing particle loops (push and weighting).

Fixed bug with number of collisions not computing correctly because
...
INT/REAL conversions.
Number of collisions now take into account the different weight of
particles inside a cell without impacting performance.

Huge improvement in reset (by increasing a little bit push time) using
...
OMP locks to assign particles to cells in the pushing step.
Trying to combine push+reset and collision+scatter did not work.

Still no solution for the reset subroutine. It is really time
consumming.

First commit of branch performance:
...
Bugs fixed:
- Solved an issue with particles being injected with infinite velocity
resulting in Inf velocity in some cells of the output files.
- Particles are now equally distributed in cylindrical geometry along
the radial direction.
New features:
- Particles now have their own weight that is recalculated when the
particle moves to a new cell. This avoid the reduction of density at
r = 0.
Cases:
- Added a case of Argon flow around a cylinder to measure performance
and future improvements.
