Merge branch 'wip/gr-noaa' of http://gnuradio.org/git/jcorgan into master

* 'wip/gr-noaa' of http://gnuradio.org/git/jcorgan:
  Added README and updated configuration requirements
  Split HRPT script into live receive and post-processing
  Dumps HRPT frames to text file similar to specification document
  Added skeleton HRPT decoder block
  Updated HRPT receiver to read files recorded as shorts
  Add HRPT word output to deframer
  Reorganization of directories
  Added HRPT deframer block
  Changed synchronizer to output sliced bits.
  Updated HRPT blocks/scripts for testing.  Seeing good minor frame sync's.
  Implemented crude timing recovery using zero crossings but no resampling
  Work in progress, incomplete
  Update rx_poes script to filter prior to PLL.
  Created new gr-noaa top-level component.
