Initial refactoring to accomodate on-the-fly variant annotation and filtering
DirSampleSource now reads from VCF files by default, we just want to read in raw variants
More refactoring, VarListManager moved to VarDisplay and is no longer a singleton
More progress on variant annotation from modular sources. Added several python scripts to import variant data into sql database
Gene details may now be read from a database. Additional springification of server side components
Fixed issue in client where filter changes didnt update variant list
SQL annotation source for genes appears functional
Refactoring variant reader for improved performance
Better documentation of ConcurrentBuffer classes
CachingSampleSource can now hold multiple samples
