SvcResult
A nevow.IContainer that has the result and also makes the input
dataset accessible.
It is constructed with an InMemoryTable instance coreResult, a table
instance inputTable, the current querymeta, and a service instance.
If a service is defined, SvcResult adapts coreResult to the columns
defined by the service (getCurOutputFields).
Original currently either is an InMemory table, in which case it gets
adapted to what the service expects, or a data.Data instance (or
something else; but few renderers will be able to handle "something
else"), which is left alone.
SvcResult also makes queryMeta, inputTable and the service available.
This should give renderers access to basically all the information they
need. The resultmeta data item collects some of those.
SvcResult objects must be able to fall back to sensible behaviour
without a service. This may be necessary in error handling.

returns the table with role.
If no such table is available, this will return an empty string.

Special descriptor for class __provides__
The descriptor caches the implementedBy info, so that
we can get declarations for objects without instance-specific
interfaces a bit quicker.
