general feedback

[AMChalkie]

I really appreciate the package.

Some quick comments:

1. Version numbering would be useful beyond 1.0.
2. Branches/releases for fixes would also be helpful.

Also, this warning comes up when installing:

Warning: replacing previous import ‘IRanges::shift’ by ‘data.table::shift’ when loading ‘goldmine’
