extended download function to sample data, split existing vep & non-cds downloads into separate files; moved update_vep_table() function into new save_data() method
bugfix: dancer_app->environment automatically becomes a config var when defined in Test::Common, otherwise needs manually adding to config (removed from form_opts)
added ability to set max x & y-axis values in chartdirector output; 02-vcf-analysis script loads ngs.locations db table for use in start position exclusions
major version change: refactored _run_vep() to select consequence, variation, sift & polyphen values from specified gene/feature combination (multiple entries for same exon_id from vep, with varying sift, polyphen, consequence & variation vals taken into hashref meant last one wins); added cds and protein annotation vals; vep data row skipped & warning issued if ENSG0000* gene id not present in transcripts db
re-arranged order of loaded modules in NGS.pm to avoid redefined var warning; moved vep results from template var to vars var; replace BioSphere::api_version with a Moo 'has' api_version to avoid error in get_cache_types() when called from NGS.pm
major upgrade - app uses vep api_version to look for available cache types (ensembl, refseq, merged) and disables any from selection if not available; results page displays api version and selected cache database; vep wrapper captures vep.pl stderr for display on results page; added vcf 'filter' col to results page; enabled HGVS notation function
