GeneralResources, SessionConfiguration, Configuration and Resources

Opus implements a few classes that are used for configuration of objects.

GeneralResources

- it is a python dictionary with some additional methods.

SessionConfiguration

- a singleton (child of GeneralResources that is to be configured with global settings for a user's session. Requires parameter in_storage to not be None if creating a new instance, so SessionConfiguration knows from where to get the data for any dataset it creates.

Configuration

- it is a child of GeneralResources that implements a hierarchical representation of the user-specified parameters and settings.

Resources

- it is a child of Configuration. It has access to the SessionConfiguration.
