Module standardcores

Some standard cores for services.

A core receives and "input table" (usually just containing the query parameters in the doc rec) and returns an output data set (which is promoted to a SvcResult in the service before being handed over to the renderer).

These then have to be picked up by renderers and formatted for delivery.
