suggest to add method to get all functon names

[abramhum]

Hi:
I recently combine treetable to my project. And add function to call all the methods name,
I suggest it can be improved and add in future, thanks a lot.
function () { var allproperties = []; for (var m in methods) { if (typeof methods[m] == "function" && methods.hasOwnProperty(m)) { allproperties.push(m); } } return allproperties; }
