/*! \brief This is a table of the all the external content locations for a given
	MPxNode.

	It is a subset of the information contained in MExternalContentInfo: it has
	as many entries, but each entry only states the key and location.

	While MExternalContentInfoTable is meant to query external content from a
    MPxNode, MExternalContentLocationTable is meant to pass modified
    locations back to the MPxNode.

	Key: Same as for MExternalContentInfoTable.

    Value: New location of the content for this entry (path, URI, ...).
