Log:
Bug #673877 - fixes and enhancements to example script account_analysis.py
a) added usage information when not enough arguments added
b) put the majority of code into an exception handling block so that if
something goes wrong the session is closed.  Prior to this change a problem
would result in a lingering lock.
