/**
* 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" }]
* }
