Packaging a working LDAP + Grouper + Delta script

[astrochun]

I have performed tests of LDAP queries, Grouper queries, and delta synchronization in the tests folder.

Next step is to package it together into a working module(s).

This is in the feature/ldap_grouper_delta branch

1. Modules will be within a DataRepository_patrons folder
2. setup.py is needed [7abba06, dd202e4]
3. requirements.txt is needed [152e664, dd202e4]
4. A primary script (script_run) to run the query [777ba4f, 306b1c8, 3303169, 4a6a103 8882d20, 1385487, aa296b8, bdb6cb3, ec10d9e, 01a5d18, 8f5dfe2, 3b636da, c6317b0, 6223407, 452aeed, d9f60df, ba1e8cb, fa48fc0, 6413065, 89af40a, 3469d3a, a64c668, fe1f397, bfe373c, e2099ad, 8d9788a, 3e1a5b0, 47e45e3, 7aa387f]
5. A config file is needed containing the CSV info [c3413f5, 2a853a7, c6b2b72, 8ef9944]
6. Add a logging module (logger.py) and use it in script_run [66821d8, 0093af9, 6413065, 433364b]
7. Update README to document the package [851780, 82643c9, 3fe29ae, 2640fe6, f78e085, 812f0ed, 262d8f7, c50fe34, 06e8bff, 210b0fd, e701bed, 69035f7, b57ba63, 8ef9944, 14c85f5]
8. A timing class to indicate duration of execution [b3a6cd5, 5f0353b, 47e45e3, 7aa387f]
9. Add a simple test that uses a test NetID account and a Grouper group to synchronize and undo. This will confirm that the code is functioning. [This is a separate issue, script_run: --test flag for quick Grouper synchronization #18]
