processBed: Processes input befile
In drashley/InvertR: Finds putative inversions in Strand-seq sequencing data

Generates a dataframe of reads from a bedfile for the specified genomic coordinate

1 2	processBed(startLoc, endLoc, chr, fileName, skip = 3, padding = 1e+05, qual = 0, rmdup = TRUE, verbose = TRUE)

`startLoc`	Genomic coordinate start position
`endLoc`	Genomic coordinate end position
`chr`	Genomic coordinate chromosome
`fileName`	Name of bamfile to process
`skip`	Number of rows in header of bedfile
`padding`	Number of bases to extend beyond the startLoc and endLoc
`qual`	Filter reads based on specified qulaity score
`rmdup`	if`TRUE` remove duplicate reads
`verbose`	Verbose messages if`TRUE`
