A fork of sublime-style-column-select without the "sticky" problems.
When dragging the mouse and with the alt key pressed, this will select a rectangular region.
This is a fork of @bigfive's "sublime-style-column-selection" Atom package, aka the project bigfive/atom-sublime-select in github, in that the core code was copied in the beginning of development.
@bigfive's package had the exact behavior I was used to from JetBrain's intelliJ IDEs. (Contrary to the implication of @bigfive's package name many IDE's used this column selection technique). I tried to use it but it had serious "stickiness" problems where the rectangular selection would not turn off. It would also come on at random times. I and others posted issues but there has been no response to my issue after two months. bigfive/atom-sublime-select#17
The "sublime-style-column-selection" code trusted browser events. It trusted the alt-key to be down or up based on the history of keydown and keyup events. It had several other similar assumptions. This version has the opposite philosophy. For example, if a mouseup or keyup event happens anywhere at any time in the entire workspace then selection is disabled.
