Merge branch 'master' into xcorr
(updated/corrected seek_record_read)
very basic x-corr is implemented.
work in progres....
added incoherent dedispersion
computer code is working (though h5py mpio didn't work too well).

Some thought needs to be done on the physics.
For instance,
* we have the two phasepols, but they are different.
Which one should we use.
* it could happen that we average both fh's in time and frequency
  which would reduce the resolution of the data. A warning is printed
  but no code has been implemented for interpolation.

* I need to double-check the order of the frequency channels
added argparse and prettied-up verbose statements.

verified mpi is working, though h5py mpio still stalls
so we disable xcorr output if size > 1
Merge branch 'master' into xcorr
added propagation delay (phase) offset for reading
the two filehandles

improved print/verbosity
pass dedisperse argument from CL
Merge pull request #17 from aberndsen/xcorr
