Reviewer to do

[karinorman]

General

• [x] deal with vignettes, either by checking that existing vignettes will pass CRAN, or creating another version with a toy ITIS that will run

• [x] add contribution guidelines (w/ URL, BugReports, and Maintainer)

Reviewer 1

• [x] examples for mutate_db and taxa_tbl, update examples for td_connect and td_create

• [x] backend descriptions in schema.rmd, and briefly in README? include info on how often database will be updated and general DWC column descriptions

• [x] add provider descriptions to README w/citations

• [x] add tests for mutate_db(), quick_db(), and has_tbl()

• [x] change by_* naming convention to filter_*

• [ ] suppress warnings from td_create

• [x] delete code for null_tibble()

• [x] option for manually closing database connection (this probably already exists but is also probably different depending on provider?)

Reviewer 2

• [x] explicitly state location of database in README? (or just point them to td_create documentation)

• [ ] test again on windows, can we replicate the issues? (install and td_create errors)

• [x] add clean common names example to mutate_db documentation

Additionally, I think we need to tackle the versioning database thing. I can try to take a crack at that... in doing so, we might want to cut a new update of some of the backends as well now. I think there's newer COL and OTT releases already, and GBIF, ITIS, NCBI are rolling updates and could probably be updated.

quickly re database disconnect -- we do have td_disconnect() but it's not currently exported (and might need documentation). I also kinda recall that issue is particularly annoying for monetdblite which doesn't allow concurrent connections, (though I think we found a workaround at some point), and shouldn't matter so much once duckdb replaces monet...)

Done. and versioning done too.
