Creates and initializes the SQLite database cache file (named @filepath{vitreous.sqlite} and located
in the project root folder) by running queries to create tables in the database if they do not
exist.

}

@defproc[(preheat-series!) void?]{

Save info about each series in @racket[series-folder] to the cache.

}

@section{Retrieving cached data}

Some of this looks a little wacky, but it’s a case of putting a little extra complextity into the

@emph{body} of a Pollen document (i.e., series pages).

that series using the same value in the @tt{noun_plural} column appear together.

}

              @defproc[(delete-notes!   [page stringish?]) void?])]{
