	To fix the bug that causes crash on Max OS X:
	
	* src/SimpleRandomizer.h
	(getInstance): Create new instance if the static variable is 
null.
	* src/SimpleRandomizer.cc
	(randomizer): Initialized to 0.
	* src/BitfieldManFactory.h
	(getNewFactory): Removed the call to setRandomizer().
	
	To fix the miscalculation of the range of checksum:
	
	* src/BitfieldMan.h
	(isBitSetOffsetRange): New function.
	* src/BitfieldMan.cc
	(isBitSetOffsetRange): New function.
	* src/SegmentMan.cc
	(tryChunkChecksumValidation): Use 
BitfieldMan::isBitSetOffsetRange().
	Use bitfield->getBlockLength() instead of segment.segmentLength.
