XML Batch Chunk Functions
`add_logit_tables_xml()`	Add a table which has definitions with logit.type to be converted to XML
`add_logit_tables_xml_generate_levels()`	Add a table to convert to XML but generate additional levels of XML nesting providing a special case for logit tables.
`add_node_equiv_xml()`	add_node_equiv_xml
`add_rename_landnode_xml()`	Add a table to an XML pipeline that instructs the ModelInterface to rename LandNodeX to LandNode.
`add_xml_data()`	Add a table to an XML pipeline to include for conversion to XML.

Constants
`GCAM_DATA_MAP`	GCAM_DATA_MAP
`LEVEL2_DATA_NAMES`	A list of column orderings keyed by the ModelInterface header so that we can ensure tables being sent to be converted to XML by the ModelInterface have their columns arranged in the order the ModelInterface is expecting them.
`PREBUILT_DATA`	A list of prebuilt data objects. These are used when the proprietary IEA energy data files are not available, and thus `module_energy_LA100.IEA_downscale_ctry` is not able to run. Its immediate downstream dependencies then used the prebuilt versions of their outputs stored in this object.
`XML_NODE_EQUIV`	A list of XML tag equivalence classes so that the ModelInterface when converting data to XML can treat tags in the same class as the same when enabled, thus not requiring multiple headers for instance to read in a share-weight into a technology intermittent-technology or tranTechnology.
