Minor coding style update.
Removed ugly table border.
Added logging messages.
added debug message, and changed list constructor syntax.
Removed redundant check for null, and added explicit exception to handler.
Added model.BasicOrganization for listing purposes.

Specifically OrganizationList didn't handle Organization objects
very well due to missing data in JSON.

Minor refactoring of model.Organization.
Created model.CallList and moved global call list to environment.
