Some functions which applies to scoped tags in general moved from TaskTag to Task model.
Also, some stylish and whitespace changes and docstrings added.
_global_ = this;
function Namespace(name, f) {
var n = name.split(".");
for (var o = _global_, i = 0, l = n.length; i < l; i++) {
o = o[n[i]] = o[n[i]] || {};
}
if (f) f();
}
