rnabioco/valr: valr 0.4.0

Minor changes

• All relevant tests from bedtool2 were ported into valr. Bugs identified in corner cases by new tests were fixed (#328 @raysinesis)

• bed_jaccard() now works with grouped inputs (#216)

• Update dplyr header files to v0.7

• bed_intersect() and internal intersect_impl were refactored to enable return of non-intersecting intervals.

• The genome argument to bed_makewindows() was deprecated and will produce a warning if used. Also error handling was added to check and warn if there are intervals smaller than the requested window size in makewindows_impl() (#312 @kriemo)

• Fixed off by one error in reported distances from bed_closest(). Distances reported now are the same as bedtools closest behavior (#311).

• bed_glyph() accepts trbl_intervals named other than x and y (#318).

• bed_makewindows() now returns the number of windows specified by num_win when the input intervals are not evenly divisble into num_win, consistent with bedtools behavior.

• The output of findOverlaps() is now sorted in subtract_impl() to prevent reporting intervals that should have been dropped when calling bed_subtract() (#316 @kriemo)
