Testing external force based acceleration + some minor typos.
Finished work on the unit conversions for the acc. frame. The stationary state is mass independent, however, it would appear that the mass dependence of the process of reaching the stationary state is incorrect. That is, it is not linear with the particle mass.
Worked on accelerated frame, there is something wrong with the units, as reduction of time step does not make particle velocity converge, and in fact makes the algorithm unstable.
