1.  Cleaned up the whitespace in bedFile.cpp and bedFile.h
	2.  Added a check in bedFile.cpp to detect if the BED file is space-delimited.

	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

	1.  Changed BedFile::loadBedFileIntoMapNoBin() to allow either "" or "stdin".
	2.  Consequently, this allows mergeBed to accept stdin as well.

	Rather self-explanatory.  Affects *Main.cpp files.
	Also affects the bedFile.cpp file.
		All of the BED entry checks now write to stderr.

Changed sortBed to allow input from stdin.
