frame64: updating synchronizer to operate like flexframesync
Merge branch 'frame64-new' of /home/jgaeddert/git/liquid-dsp into frame64-new
detector: adding autotests
framing/detector: computing number of internal correlators necessary

  * create() method allows user to specify maximum carrier offset
  * internally need to compute number of correlators necessary
  * improves computation for shorter sequences
  * degrades performance for longer sequences
framing/detector: adding more autotests (odd lengths)
doc/detector: adding script to simulate detector performance
gmskframe: removing phasing pattern from generator
gmskframe: changing from default p/n sequence
gmskframe: updating license on gen/sync files
gmskframe: completely gutting frame synchronizer

  * removing nearly all internal object members
  * fixing frame properties internally (k,m,BT)
  * moving member function definitions from header
  * block commenting large portions of code
  * need to create frame detector
gmskframe: re-structuring frame generator

  * four simple parts: preamble, header, payload, tail
  * fixing ramp up/down for symbols
  * moving internal member definitions from global header
gmskframe: creating/initializing frame detector object
gmskframe: adding methods to synchronizer; needs tesing

  * method to update instantaneous frequency estimate
  * method to push through matched filter (symsync)
  * method to push symbols through preamble synchronizer
gmskframe: adding method to receive and synchronize preamble

  * still needs a lot of work
  * saved samples don't match known p/n sequence
  * probably due to sample timing
  * delay of one sample due to instantaneous frequency estimate
gmskframe: increasing BT; trying to align decimator
gmskframe: synchronizer now computes proper matched output
gmskframe: synchronizer decoding header
gmskframe: decoding payload in synchronizer
gmskframe: cleaning interface, re-simulating performance in AWGN
gmskframe: adding pre-processor option for pre-demodulation filter
