+Read Only ByPass
+================
+This Module provides a solution to the problem of the interaction between
+'readonly' attribute and 'on_change' attribute when used together
+
+Behavior: add `readonly_fields` changed by `on_change` into the fields passing
+into an update or create. If `filter_out_readonly` is into the context and set
+True then apply native behavior.
