This function squashes differences between the last TFS commit and HEAD into one TFS-checkin and mark it as descendant of both previous TFS-checkin and HEAD.
It works similarly to checkintool, except checkintool launches the standard TFS checkin window.
checkin command differs from rcheckin in that the latter mirrors a series of commits into TFS instead of squashing them into one.
