- * name: $.fn.formValues

- * docs: Gets form values and creates a key=>value array of the found values.
- * Optionally adds the button which is clicked if you provide it.
- * Only does this for ENABLED elements in the order of the form.
+ * Initial frontend function to submit form variables. This function
+ * is for registering coordinates, in the case of an image being used
+ * as the submit element, and sets up an event to listen and wait for
+ * a form submit click. It then calls any following chained functions
+ * to actually gather the variables and submit them.
+ *
+ * Usage examples, when used with getForm().putForm():
+ *
+ * 1. Just eval the results returned from the backend.
+ * $('#form-id').form();
+ *
+ * 2. Render backend results directly to target ID (expects (x)HTML).
+ * $('#form-id').form('#target-id');
+ *
+ * 3. Submit to backend URL (form action) then call this function.
+ * $('#form-id').form(post_callback);
+ *
+ * 4. Load target ID with backend results then call a function.
+ * $('#form-id').form('#target-id', null, post_callback);
+ *
+ * 5. Call a browser function (for validation) and then (optionally)
+ * load server results to target ID.
+ * $('#form-id').form('#target-id', pre_callback);
+ *
+ * 6. Call validation function first then load server results to
+ * target ID and then also call a browser function.
