Create an mdb merging function to merge multiple mdbs into one

[DemevengDerrick]

This function will take in a directory to the folder containing mdb files, and a target table name. It will then loop through all the mdbs, extracting the tables and merging them into one.

• Create the pseudo code for the function
• Create the function to do the merging
• Document the function
• Create tests for the functions and integrate into the poliprep package
