INGEST - actually ingest files from an ndi_document file_info into a database
[B,MSG] = ndi.database.implementations.fun.ingest(SOURCE_FILENAME_LIST, ...
DESTINATION_FILENAME_LIST, TO_DELETE_LIST]);
Ingest files into a database. SOURCE_FILENAME_LIST, DESTINATION_FILENAME_LIST, and
TO_DELETE_LIST are typically returned from ndi.database.implementations.fun.ingest_plan().
SOURCE_FILENAME_LIST are a list of the source files to be copied, and DESTINATION_FILENAME_LIST
are a list of locations to be written to. TO_DELETE_LIST is a list of files to be deleted.
B is 1 if the operation is successful, 0 otherwise. MSG is empty ('') if there is no error and
contains a description of the error that occurred if there was an error.
