get_SDA_property: generic aggregation of arbitrary component or chorizon child tables #427
Description
This issue is a follow up from discussion in #399 to create a generic interface for child table aggregation at either the component or chorizon level
Example use cases that would be supported:
- Sum of Component Surface Fragment Cover %
- Sum of Component Horizon Fragment Volume %
- ...
Standard SQL aggregations like SUM/MIN/MAX/AVG would be able to be selected as needed. Possibly we could support some other custom functionality like a weighted average, but would need to add an argument to handle the weights column.
