Shorthand operator for NULL fallback

internal

When added to an existing shiny app, users may subset any
developer-chosen R data.frame on the fly. That is, users are empowered to
slice & dice data by applying multiple (order specific) filters using the
AND (&) operator between each, and getting real-time updates on the number
of rows effected/available along the way. Thus, any downstream processes
that leverage this data source (like tables, plots, or statistical procedures)
will re-render after new filters are applied. The shiny module’s user interface has
a 'minimalist' aesthetic so that the focus can be on the data &
other visuals. In addition to returning a reactive (filtered) data.frame,
'IDEAFilter' as also returns 'dplyr' filter statements used to actually slice
the data.
