Detailed Description

ActionDarkSolver checks basic dark set constraints for an action that either (1) sources are of one container: all aligned. Also, we need to ensure that other allocated bits in the container will not be corrupted, and since set instruction on mocha/dark are whole-container-set, all other bits that are not set in this action need not to be not live.
