1. Fixed bug where an extra tab is inserted prior to \n in the report*Newline methods.
	2. Fixed bug causing incorrect behavior when first bed feature has stant and end = 0.

	A. Fixed massive bug in parseBedLine that disallowed BED features with start = 0.  Bad news.
	1. Moved ToString to lineFileUtilities
	2. Added tabFile class.  Works with gzip as well.
	3. Changed groupBy to use the new TabFile class.
	4. Added new collapse feature to groupBy.

	1.  Added support for VCF 4.0.  BED.end is based on the size of the REF allele in the VCF entry.
	2.  Fixed a bug in BamReader.cpp that bombed when seq and qual are == "*"
	3.  Changed the Makefiles to inherit flags from the master Makefile in the root directory.
	4.  Fixed a bug in bedToBam to created incorrect CIGAR strings for the first block.

	Ready for publication release.
	Checked all of the help messages.
	Cleaned up some inconsistencies.

	1.  Changed master Makefile to compile utils first.
	2.  Fixed obvious bug in calculating discrete DOC in genomeCoverageBed
		--Identified by Scott Dewell, Rockefeller University.  Thanks!

	1. Added strandedness to relevant programs (e.g. intersectBed, mergeBed, etc.)
	2. Moved reportBed and reportBedRange to bedFile.cpp to clean up code
	3. Sped up file parsing.  Added lineFileUtilities.cpp
	4. Added peIntersectBed

	1.  Added subtractBed.
		A. Fixed bug that prevented "split" overlaps from being reported.
		B. Prevented A from being reported if >=1 feature in B completely spans it.
	2.  Added linksBed.
	3.  Added the ability to define separate windows for upstream and downstream to windowBed.

	1.  Added a README for installation
	2.  Modified intersectBed and windowBed to call one function for
	    finding overlaps.  This function is now called when reading
	    from cin or from a file.
	3.  Added acknowledgements.
	4.  Corrected the PROGRAM_NAME in coverageBed
