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.

Tweaks to processHits in intersectBed for speed.

	The overlap variable was a CHRPOS.  The negative overlaps were reported as positive causing
        false hits when using BAM input.

Fixed bug in groupBy and added logic to enforce that strings are numeric when asking for nueric ops.

	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. Fixed bug in BamAncillary::getBamBlocks where the switch statement was misbehaving.  Changed to if/else
	2. Added countSplitHits to bedFile class to proper count coverage from "blocked" alignments. Previously, coverage
           was counted separately for __each__ block yet what we actually want is the base coverage to be counted for each block,
           but we only want the blocks to be treated as __one__ alignment or feature.
	3. Updated coverageBed to use getBamBlocks.
