some simulators support post processing, others don't. looking for a
common denominator appears to be a dead end to me. let's do this
outside, and just once. this should be possible -- even without
noticeable performance loss.

.dat files should be deprecated in favor of a plain data interface
between a simulator (or just a raw file) and the ui. i have started to
work on this, it's currently suspended, waiting for the "external
simulator" merge. Guilherme suggested to make it part of a
postprocessing library, which probably makes sense, once it is there.

this is a non-issue, once we have a unified data structure for the
various backends. when done right, supporting data from any simulator is
similar to support for multiple data file formats (thinking of hdf5, and
a myriad of others).
