read_prompt

This is a small helper used by the GoFigr configuration wizard to collect
user input interactively. When a validation function is supplied, the input
will be repeatedly requested until it passes validation or the maximum
number of attempts is reached.

Integrates with your 'RMarkdown' documents to automatically publish
figures to the <https://GoFigr.io> service. Supports both 'knitr' and interactive
execution within 'RStudio'.
