Mark Nelson	b62b5879af	MDL-56046 core_dataformat: added functions to support multiple sheets ... Also removed write_header() and write_footer(). The reason for this is because in core we want to know if the format being used supports multiple sheets. To do this, and ensure we do not break third-party dataformat plugins, we are using method_exist(). If write_header() and write_footer() remain in the base class then this will always be true.	2017-06-26 13:29:32 +08:00
