Input:
api - which odbc api to use. originally we only used adodbapi but had
problems with that on VMs so added pyodbc, which seems to work
better but I didn't want to chance breaking all the old stuff
Output: cnctn - connection to NLPdev database on ghriNLP server
Functionality: Creates a connection to NLPdev on ghriNLP
History:
12/30/10 - created
7/13/11 - added api input and modified to use pyodbc as well
7/27/11 - added warning logging message for using adodbapi from some
machines at GHRI
