Easy-to-Use, Dependencyless Logger
Description
An easy-to-use 'ndjson' (newline-delimited 'JSON') logger.
It provides a set of wrappers for base R's message(), warning(), and
stop() functions that maintain identical functionality, but also log
the handler message to an 'ndjson' log file.
No change in existing code is necessary to use this package,
and only a few additional adjustments are needed to fully
utilize its potential.
