// Then, later in your code you can do the following:

//GET to /buildings/123/evaluate?myParam=param with headers myHeader: value
//Signature for this "custom created" methods is (params, headers, elem)
// If something is set to any of this variables, the default set in the method creation will be overrided
// If nothing is set, then the defaults are sent

//GET to /buildings/123/evaluate?myParam=param with headers myHeader: specialHeaderCase
