Replicate subpackage structure

[huard]

Description

Some processes use a hierarchical naming convention (CDAT.aggregate). I suggest we mimic this by creating this mock hierarchy, ie. wps.cdat.aggregate instead of sanitizing names to cdat_aggregate

... this means we would generate a namespace with "artificial" packages? It needs to be a valid Python expression.

There is unfortunately no recommendation or restriction how to define WPS identifiers. All we know is, we get a string ;) We can try to establish a "good practice" for our own services ... but in case of birdy, we need to be fail-safe.

Yes

and that's a problem. We probably should have a dictionary accessor where the original name of the process is conserved.

Maybe we need to think about this more.
