// Using abbreviation of DotToString = DTS
if (typeof DTS == "undefined")
{
	var DTS = {};
}

// Make a function for creating namespaces
DTS.namespace = function() {
	var a=arguments, o=null, i, j, d;
	for (i=0; i<a.length; i=i+1) {
		d=a[i].split(".");
		o=DTS;

		// DTS is implied, so it is ignored if it is included
		for (j=(d[0] == "DTS") ? 1 : 0; j<d.length; j=j+1) {
			o[d[j]]=o[d[j]] || {};
			o=o[d[j]];
		}
	}

	return o;
};

and thats all

Now you can create your own namespaces like this:

// We can mention our top level namespace
DTS.namespace("DTS.UI.Example");

// or we can just skip top level namespace
DTS.namespace("UI.widgets");

// or we can have a hybrid case
DTS.namespace("DTS.UI.Example", "UI.widgets");
