Bulk Creation of Analytic Output Mappings

[kdjones]

This is more of documentation for an enhancement than an issue. Generally, if the desired output is known in some format (i.e. a network model), it would be useful to have a way to bulk create the signals and output mappings for the analytic.

Filter statements, etc enable bulk creation of input mappings but there really isn't an analogous way to accomplish that with output - essentially why a network model, or file containing instructions would be useful.

One major use case would be the LSE. However, instead of directly depending on the Network Model, perhaps it is worth defining an intermediary file structure that can be created by the analytic developer that the openECA could take and auto-generate the signals/mappings for. Perhaps there is already much of the moving parts for this defined as part of the Mapping classes themselves?
