This script takes a directory with EXFOR masterfiles and stores augmented EXFOR subentries in a MongoDB database. The directory has to be specified in the script by replacing the string <PATH TO DIRECTORY WITH EXFOR ENTRIES> with the actual directory.

In more detail, the script accomplishes the following:

1. Read in the EXFOR masterfiles
2. Convert energy units to MeV and cross sections to millibarn
3. Merge the first subentry of each entry into the following subentries
4. Convert the augmented subentry to a JSON object
5. Add these JSON objects to a MongoDB database

This script relies on the functionality of the packages mongolite, data.table and exforParser. The unit conversion and merging of subentries is implemented in the function transformSubent of the exforParser package.
