1. Reset BED.strand to be string instead of char in the interest of generality.
	2. Fixed bug in genomeCoverageBed where NULL entries where genome summaries were err. reported with -bga.
	3. Fixed bug in closestBed where NULL entries were err. reported when BED > 6.
	4. Standardized the Open, Get, Close idiom per improvements from Gordon Assaf.
	5. Add "split" logic to bamToBed.

	1. Fixed bug to "re-allow" track and "browser" lines.
	2. Fixed bug in reporting BEDPE overlaps.
	3. Fixed bug when using type "notboth" with BAM files in pairToBed.
	4. When comparing BAM files to BED/GFF annotations with intersectBed or pairToBed, the __aligned__ sequence is used, rather than the __original__ sequence.
	5. Greatly increased the speed of pairToBed when using BAM alignments.
	6. Fixed a bug in bamToBed when reporting edit distance from certain aligners.

	1. The start and end coordinates for BED and BEDPE entries created by bamToBed are now based on the __aligned__ sequence, rather than the original sequence.  It's obvious, but I missed it originally...sorry.
	2. Fixed a bug in bamToBed that caused a crash when created BED / BEDPE from "spliced" BAM alignments.
	3. Added an error message to mergeBed preventing one from using "-n" and "-nms" together.
	4. Fixed a bug in pairToBed that caused neither -type "notispan" nor "notospan" to behave as described.

	1. atoi fails in parseLine when start = 0.  Changed to strtol.
	2. modified parseBedLine and parseGffLine to do better sanity checking.

  Rewrote complementBed to use a slower but much simpler approach. This resolves several bugs with the previous logic.

   This becomes the new model for handling files/stdin,
   rather than duplicating the main logic of each porgram
   in a block for files and a block for stdin.

   Much slicker.

	Fixed a bug in closestBed that caused all nearby (not just closest) features to be returned.

	1. Updated the mergeBed documentation to describe the -names option which allows one to report the names of the
	features that were merged (separated by semicolons).

   Changed windowBed to optionally define the left and right windows according to
   strandedness.

The memory usage is now less than 2.0 Gb.

	Fixed an obvious bug in subtractBed causing incorrect behavior when
	two features in B overlapped with a feature in A.
