Notes
This function works around a problem with calls to document.getElementById() where sometimes, nodes with a name matching the id will be returned. This function will throw an error with a descriptive message if that happens.
Example
var titleNode = fluid.byId("titleNode");
In this example, fluid.byId() will return the node found with an id attribute equal to "titleNode."
