Allow the user to enter a command to execute

[JeffTeter]

The command will be in the form "PYREVISE {file name} {list of dictionaries}"

The user should be able to use a "GET-LIST" to select a group of records to be updated. If no list is active, the user should be prompted for a record ID repeatedly until the record ID is null.

If the user enters "NEW" for the record ID, the program should check for the existence of a "&NEXT.AVAILABLE&" dictionary and, if found, increment it by one. If that dictionary is not found, the user should be prompted for a record ID.
