Revision 0.4.0, released on XX-03-2020¶

Introduced Jinja2 templates for code generation.

This change significantly refactors the way how code generation works. Previously, pysmi code generator has been responsible for producing a well-formed text document (e.g. JSON or pysnmp).

With this change, all code generations should be done through Jinja2 templates by rendering them in the context of the parsed MIB taking shape of the intermediate MIB representation which other parts of pysmi provide.
By way of moving pysnmp code generation to Jinja2 template, the Python code layout of pysnmp modules improved dramatically - it is just one little step from being PEP8-compliant.
The template-based pysnmp code generator drops some backward compatibility aids that keep Python MIB modules compatible with older pysnmp versions. Perhaps in the followup patch we should make the Python MIB module failing early and clearly on import when it’s old pysnmp importing it.
Jinja does not seem to work well with Python < 2.6 and Python == 3.2. Despite pysmi is trying to support those Python versions, it may start to fail on them due to Jinja failures.
Introduced SNMP agent code hooks generation template allowing building a functional skeleton of the Python module from a given ASN.1 MIB. The tapping points include SMI Managed Object read/readnext/write/create and destroy work flows.
