Added aaaaaa to the file.
Reverted.
Changed the `get_download` function so that each depth gets a count row, regardless of whether or not any palynomorphs were recorded.  If no palynomorphs were recorded at depth X then the row is included (with an associated row ID), but it is filled with NA values rather than 0s.
