Arguments:
arg1, required: glob to fastq files
site=[pattern] perl-style pattern of the restriction site to recognise, in single quotes.
		default is BcgI: \'.{12}CGA.{6}TGC.{12}|.{12}GCA.{6}TCG.{12}\'
		if you need AlfI, here is how to define it: \'.{12}GCA.{6}TGC.{12}\'
adaptor=[dna sequence] adaptor sequence to look for on the far end of the read. 
		Default AGATC
sampleID=[integer] the position of name-deriving string in the file name
					if separated by underscores, such as: 
					for input file Sample_RNA_2DVH_L002_R1.cat.fastq
					specifying arg2 as \'3\' would create output 
					file with a name \'2DVH.trim'	
barcode2=[integer] length of the in-line barcode immediately following
