Note that the REM generation is very demanding, in particular:
* the run-time memory consumption is approximately 5KB per pixel. For example,
a REM with a resolution of 500x500 needs about 1.25 GB of memory, and
a resolution of 1000x1000 needs about 5 GB (too much for a
regular PC at the time of this writing).
a REM with a resolution of 500x500 would need about 1.25 GB of memory, and
a resolution of 1000x1000 would need needs about 5 GB (too much for a
regular PC at the time of this writing). To overcome this issue,
the REM is generated at successive steps, with each step evaluating
at most a number of pixels determined by the value of the
the attribute ``RadioEnvironmentMapHelper::MaxPointsPerIteration``.
* if you generate a REM at the beginning of a simulation, it will
slow down the execution of the rest of the simulation. If you want
to generate a REM for a program and also use the same program to
