tiny-count: changes to anchored selector semantics, and user experience improvements for overlap selectors #281
Description
Now that tiny-count supports shift parameters for overlap selectors, we are changing the semantics of 5' anchored, 3' anchored, and anchored overlap selectors to require nesting of the non-anchored end of the alignment within the feature's interval.
Shift parameters can produce illegal feature intervals. Currently we simply drop these feature-rule pairs without notifying the user. This behavior needs to be further developed so that the user is notified of the specific matches that were dropped and why.
To further improve the user experience with overlap selectors, "full" will be renamed to "nested", and the overlap column in the Features Sheet will support wildcard keywords (any, all, *, and an empty cell) so that users don't have to specify "partial" in fully permissive rules
