| /** |
| * massload configuration |
| * |
| * It is possible to set this to a standard jQuery-like AJAX config. |
| * In addition to the standard jQuery ajax options here you can supply functions for `data` and `url`, the functions will be run in the current instance's scope and a param will be passed indicating which node IDs need to be loaded, the return value of those functions will be used. |
| * |
| * You can also set this to a function, that function will receive the node IDs being loaded as argument and a second param which is a function (callback) which should be called with the result. |
| * |
| * Both the AJAX and the function approach rely on the same return value - an object where the keys are the node IDs, and the value is the children of that node as an array. |
| * |
| * { |
| * "id1" : [{ "text" : "Child of ID1", "id" : "c1" }, { "text" : "Another child of ID1", "id" : "c2" }], |
| * "id2" : [{ "text" : "Child of ID2", "id" : "c3" }] |
