This is a fix for #498 It supports operations that should consider groups by using three methods: - group_by + agg + explode - group_by + lazy frame operations like `head` and `tail` - `col(*)` + operation + `over(groups)` which is a window function.

This is a fix for #498
Most of the operations that we had and should work with groups are now supported. The only remaining is the
sample/3, which may add to this PR soon.EDIT:
sample/3is giving me an error that I can't understand. I will merge this without that function. I should revisit later.
