1. Writing BEDPE now requires a BAM sorted/grouped by query.
	2. BEDPE output respects CIGARs on both ends.
	3. End coordinates for all output formats respect CIGAR.
	4. Default score for BEDPE is min mapping quality.

	1. Added an enum for BED line status in an effort to handle
           header and blank lines in an input file.
	2. Modified the Open/Get/Close idiom to only test against
           BED_INVALID status.  Only intersectBed and bedFile.cpp
           were updated.
	3. Added AddBamTag to BaumAux.h
	4. Wrote bamFillMateSeq

	- also standardized the naming convention for private variables.
	- loadIntoMap methods use Open/Get/Close idiom.

Added new version of BamTools and fixed a couple minor bugs in intersectBed that were caused by the branchmerge.

	- Allows one to report 0 overlap for non-overlapping A features
	- Changed all private memeber variables to use "_VAR" notation.
	- Added convenience functions for reporting overlaps.

	1. Can parse CIGAR string.
	2. Output looks roughly correct.  Need to continue testing.

	1. Added the -hist option (credit to Jose Bras).
	2. Substantially improved the speed by using a depth iterator instead of copying the depth map for each feature in B when computing coverage.

	1. Added the -wo option to intersectBed.
	2. Added the -s option to fastaFromBed.

	Now using a map to track the unique names of the features in a merged block.
	The consequence is that names will not be reported in the order they were added.

	Fixed an insidious bug that caused malformed BAM output from intersectBed and pairToBed.  The previous BAM files worked fine with samtools as BAM input, but when piped in as SAM, there was an extra tab that thwarted conversion from SAM back to BAM.  Many thanks to Ivan Gregoretti for reporting this bug.  I had never used the BAM output in this way and thus never caught the bug!

	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.
