Creates and manages a provenance graph corresponding to the 
    provenance created by the 'rdtLite' package, which
    collects provenance from R scripts.  'rdtLite' is available on CRAN.
    The provenance format is an extension of the 
    W3C PROV JSON format (<https://www.w3.org/Submission/2013/SUBM-prov-json-20130424/>).
    The extended JSON provenance format is described 
    in <https://github.com/End-to-end-provenance/ExtendedProvJson>.

R functions to access provenance information collected by 'rdt' or 
    'rdtLite'.  The information is stored inside a 'ProvInfo' object and can be 
    accessed through a collection of functions that will return the requested 
    data. The exact format of the JSON created by 'rdt' and 'rdtLite' is described 
    in <https://github.com/End-to-end-provenance/ExtendedProvJson>.

Reads the provenance collected by the 'rdtLite' or 'rdt' packages,
    or other tools providing compatible PROV JSON output, created by the
    execution of a script or a console session, and provides a human-readable
    summary identifying the input and output files, the scripts used (if any),
    errors and warnings produced, and the environment in which it was executed.
    It can also optionally package all the files into a zip file.  The exact
    format of the PROV JSON file created by 'rdtLite' and 'rdt' is described
    in <https://github.com/End-to-end-provenance/ExtendedProvJson>.  More
    information about 'rdtLite' and associated tools is available at

Uses provenance collected by 'rdtLite' package or comparable tool
    to display information about input files, output files, and exchanged files
    for a single R script or a series of R scripts.

Displays provenance graphically for provenance collected by the 'rdt' or
  'rdtLite' packages, or other tools providing compatible PROV JSON output. The exact 
  format of the JSON created by 'rdt' and 'rdtLite' is described in 
  <https://github.com/End-to-end-provenance/ExtendedProvJson>.  More information about
  rdtLite and associated tools is available at <https://github.com/End-to-end-provenance/>
