Qsnp qio

[ChristinaXu2017]

Description

Update qSnp:

• delete commented code in qsnp.
• org.qcmg.tab.* is replacing by qio.record.* which is created on pull request create universal reader and writer #209
• move org.qcmg.pileup.QSnpRecord from qio to org.qcmg.common.model.QsnpRecord. Here QsnpRecord is similar to other qcommon::model classes, such as QSnpGATKRecord, BLATRecord, which used by multi projects but not only belong to IOs.

here we should also consider issue #231. We are not sure whether we should delete both QSnpRecord and QSnpGATKRecord on the next pull request.
