 Primary Javascript file.
 Functions are namespaced using "SEL" and functions are called using
 the syntax: SEL.functionName(params);
 Ensure that any new functions are placed within the outer "return" block,
 and that each function is terminated with a "," (except for the last
 function), ie:
 functionName: function(a,b,c) {
 var x =  a + b + c;
 ..
