Added scripts to perform automatic QC validation of MiSeq and HiSeq runs...

....
MiSeq runs don't have Read1 and Read2 elements in runParameters.xml. HiSeq runParameters.xml also have Reads element, but at a different location ($self->{RUNPARAMS}->{Setup}->{Reads}). I could change the code to parse HiSeq runs the same way as MiSeq runs (with a path modification), but it seemed simpler to extract Read1 and Read2 elements from HiSeq runs.
