pymisha

Use when importing external data (WIG / bigWig / BED / TSV / BAM / 2D contacts / array matrices) into a pymisha track DB, when picking which `gtrack_*import*` / `gtrack_create_*` / `gtrack_liftover` / `gtrack_copy` variant to call, or when a track import fails opaquely or produces an all-zero / all-NaN track.
