Composite Strata By Beds

This command composites strata within a drillhole based on bed name and key/non-key status. All the non-key strata with a matching bed name that are above the first key strata are composited and assigned the name strata_top. The non-key strata between the key strata are composited as strata_parting. The key strata with a matching bed name are composited as strata_key. The non-key strata below the last key are composited as strata_bottom. This compositing method is the same the StrataCalc uses for processing strata with bed names. The strata qualities will be weight averaged by thickness, giving one value for each attribute.
