mandatory GMOCClient.serviceURL parameter is not required by __init__()

[chaos@bbn.com]

The code:

data = gmoc.GMOCClient()
...
data.store(pop)

fails with:

Traceback (most recent call last):
  File "./report_foam_relations", line 337, in <module>
    data.store(pop)
  File "/home/chaos/gmoc.py", line 1762, in store
    wsEndpoint = self.serviceURL + '/xchange/webservice.pl'
TypeError: unsupported operand type(s) for +: 'NoneType' and 'str'

Either:

1. The code should provide a default value for serviceURL (e.g. the production URL)
2. The GMOCClient init should fail with an error when no URL is provided

Kevin will have validator check for a string or a url.

[sedwards@bbn.com]

Validator now says:

ValueError: serviceURL must be a valid URL  

When I put serviceURL in, it says:

ValueError: username must be a valid string

When I put username in, it says:

ValueError: password must be a valid string

When I put password in, it works.

So this looks fixed. Closing.
