prov_wrapup: Wrap up provenance tracking
In oharac/provRmd: Track Provenance Within R Markdown scripts

This function complets the provenance tracking by capturing the provenance info for the parent script, as well as the session and system info. This is saved to the provenance log file. An optional footer is created (by default) including a brief session/system summary, workflow chart, and table of inputs/outputs. If a footer is desired, this function should be called inside a code chunk with chunk option: results = 'asis'
