* Made method descriptions imperative: "Do this" rather than "Does this" * Changed use of "this object" to "the object" in method documentation * Added missing documentation * Fixed incorrect documentation * Fixed incorrect debug method names (as in those VeDmClassName tags we add to functions so they make sense when dumped into in the console) * Normalized use of package names throughout * Normalized class descriptions * Removed incorrect @abstract tags * Added missing @method tags * Lots of other minor cleanup Change-Id: I4ea66a2dd107613e2ea3a5f56ff54d675d72957e
