atsc: adjustments to atsc to start to conform to v3.7 structure.

Not going to comply completely with the new structure; just wanted to get it so that it looked more consistent once installed.

-Decoding ATSC using 19.2MSps rate over 5 processes
---------------------------------------------------
-
-1) Verify signal, adjust antenna and find best gain setting using uhd_fft.py,
-station frequency from the fcc video database, and sample rate to 6.4e6.
-
-2) Capture data - adjust gain (-g) frequency (-f) and which side
-the tvrx is on to fit your local setup:
-
-uhd_rx_cfile.py -s --samp-rate=6.4e6 -g 65 -f 503e6 atsc_data_6-4m_complex
-
-You probably still need fast disks to take the data, like a raid-0 set of
-striped sata drives. Make sure there are no or very few Ou overruns. Saving
-the raw usrp data in 'short' form halves the disk space/bus bandwidth that
-the usual complex form uses.
-
-3) Make pipes:
-
-mkfifo /tmp/atsc_pipe_1
-mkfifo /tmp/atsc_pipe_2
-mkfifo /tmp/atsc_pipe_3
-mkfifo /tmp/atsc_pipe_4
-mkfifo /tmp/atsc_pipe_5
-
-4) In seperate windows run processes:
-
-./interp_short.py <input rf data at 6.4Msps>
-./xlate.py
-./fpll.py
-./btl-fsd.py
-./viterbi-out.py <output mpeg transport stream>
