Zen generation tools

[KGOH]

There often is a need to generate zen definitions, i.e. namespaces and symbols. Currently each such task implements a zen namespace building and spitting

It would be good if zen provided functions like:

• define-namespace
• define-symbol
• spit-namespace/spit-namespaces (create new files with selected zen namespaces)
• update-namespace/update-namespaces (append new parts to some existing file)

Use-cases:

• generate zen schemas
• generate zen definitions using some custom tag (i.e. generate http routes)

Urgency: low
This is just an inconvenience. I can keep reimplementing spit-namespace
