Version 1.0
~~~~~~~~~~~
* ******* NOTE CHANGES TO THE API *********
* Changed parameter in createVDIFHeader (pass size of dataarray not full
	VDIF frame).
* Changed function of getVDIFEpoch and setVDIFFrameSecond
* Renamed:
	getVDIFMJD
	getVDIFFrameFullSecond -> getVDIFFrameEpochSecOffset
	setVDIFFrameSecond -> setVDIFFrameEpochSecOffset
	setVDIFFrameFull
	setVDIFMJDSec -> setVDIFFrameMJDSec
	getVDIFDMJD -> getVDIFFrameDMJD
	setVDIFTime -> setVDIFFrameTime (and changed functionality)
	setVDIFEpoch -> setVDIFEpochMJD
* Added
	getVDIFFrameMJDSec
	setVDIFEpochTime
* Added new utility printVDIFgaps to examine a VDIF stream for missing data
* vdifmux now fed by a structure.  This allows for safer, faster and more
	flexible muxing.
* printVDIFheader: when legacy data don't print any EDV info
* multi2singlethreadVDIF: fixed bug where frames with invalid bit set had zero epoch and wrong seconds
* captureUDPVDIF: properly use skipbytes at the front and back of the packet
* Version for DiFX-2.4, Nov 4, 2014

Version 0.6
~~~~~~~~~~~
* Post DiFX-2.3
* Expose getVDIFEpochMJD: returns integer MJD corresponding to start of VDIF epoch
* Add printVDIFheader which will also print contents of EDV1 and EDV3 

Version 0.5
~~~~~~~~~~~
* Fix the 2-bit 16 thread case in the vdifmux function
* 1-bit corner turners now supported: 1, 2, 3, 4, 5, 6, 7, 8 threads
* 2-bit corner turners now supported: 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 16 threads
* 4-bit corner turners now supported: 1, 2, 3, 4, 5, 6, 7, 8 threads
* 8-bit corner turners now supported: 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 16 threads
* add corner turn test program: testcornerturners
* add function to decode data from a single frame of VDIF data
* add utility to convert from 2-bit to 8-bit VDIF data (perhaps useful for testing)
* Version for DiFX-2.3, Dec 20, 2013

Version 0.4
~~~~~~~~~~~
* Add new vdifmux function which takes a multi-threaded VDIF buffer, looks
  for frames with certain threadIds, and multiplexes them into a single-
  threaded output buffer.
* New programs exercising new library routines:
  - vsum       summarize contents of 1 or more VDIF files
  - vmux       multiplex a multi-thread VDIF file into a single-thread file
* New utilities (mirroring functionality of mark5access utilities):
  - vdifd      (m5d)
  - vdifbstate (m5bstate)
  - vdiffold   (m5fold)
  - vdifspec   (m5spec)
* Other new utilities
  - extractVDIFThreads: gets only packets corresponding to given thread IDs
* Inlinification and constification of many VDIF header access functions
* Large file clean (I think) now...
* Fix bugs in multi2singlethreadVDIF which caused crashes if many packets missing
* Version for DiFX-2.2, May 31, 2013
