Lambda, stacking, and InstantAction documentation for Actions #131
Description
Right now the Actions docs only explain the most verbose possible way of defining an Action. This leads many teams to assume that is the only way and make many redundant classes for all of their needed Actions. It would be really helpful if InstantAction, defining regular actions with lambdas, and making actions that wrap other actions were documented as well so that teams knew how to concisely write actions and sequences.
