• Type: Improvement

Description

Allow a ParameterContext to contain an ordered list of other ParameterContexts, giving it the ability to inherit parameters from them. Parameter overriding logic would be as follows:

1. Parent parameters have top priority
2. Child parameters have next priority, in order from top to bottom of the ordered list

This prioritization is recursive, so grandchild parameters would have the next priority, etc.

Other considerations:

• Although write access should be unchanged, read access to a Parameter Context will now require read access to all child Parameter Contexts.
• Parameter Context hierarchy loops should be detected.
• A Parameter Context cannot be added as a child if it would change the sensitivity of any of the existing parameters.
