checkAndApply method of the RTRDataCaptureProfileBuilder protocol
Submits the configured profile for use in the data capture service.
This method should be called after all your modifications to the profile are completed. If this method call is successful, the service is ready to capture custom data fields as specified by the profile.
The method returns nil if the profile was applied successfully. If there were some problems (for example, the regular expression is not valid), the error object is returned instead.
