+If you like to use ```["*"]``` as a form, or aren't in control of the form definitions
+but really need to change or add something you can register a *post process*
+function with the ```schemaForm``` service provider. The post process function
+gets one argument, the final form merged with the defaults from the schema just
+before it's rendered, and should return a form.
+
+Ex. Reverse all forms
+```javascript
+angular.module('myModule').config(function(schemaFormProvider){
+
+  schemaForm.postProcess(function(form){
+    form.reverse();
+    return form;
+  })
+
+});
+```
