Moved the test files, killed the `check_tables` to ensure we're not looking to static files with the package.  Moved the parameters for `compile_list` up in the documentation.  Added the test for 'ageold' and 'ageyoung' to `get_datasets`.  Modified help in the `get_geochron`  and changed `writeLines` to `message`.
Made some explicit calls to column names in `get_download` to avoid numeric pointers that might lead to errors.  Changes in the `import` fields for `get_publications`.

Moved the Geochron ID into the record and fixed a typo so that geochron type now returns the correct value.  It was previously trying to match to `GeochronID`, not `GeochronTypeID`.
Moved the tests into a test folder.  Re-built package with the newest R version (3.10) and upgraded versions of `roxygen2` and `testtat`.
