Detailed Description

Randomly refine (or coarsen) an Element in each dimension.

You can specify a probability for each possible amr::Flag. It is evaluated in each dimension separately. Details:

Probabilities are specified as integer weights. The probability for an amr::Flag is its weight over the sum of all weights.
Flags with weight zero do not need to be specified.
If all weights are zero, amr::Flag::DoNothing is always chosen.
