Move templates to (temporary) new structure

Ideally each template should be under each technology dir but
the way the generic generator is written now, it assumes everything
under one directory.  For now, it can stay like this (but under
the output_filters directory).

-* Write templates according to (some, not all) node types.  You can call `gen(node)` or `gen(node, <Template>)` from within a template - see details below.  Templates must be under a specific sub-directory of `<project-dir>/ifex/templates` and must be named with the naming convention such that the node type is mentioned first (see template chapter).

 * Once the template directory is known, ee-initialize the TemplateDir object if needed.  This will populate the default templates data structure such that gen() knows which template to use.  It automatically uses the naming of the templates to know which template is for which node type.
 * Implement the `gen()` function, normally by delegating directly into `ifex_generator.gen()`, but you can put your own logic here if needed.
 * Set the jinja environment, passing in the gen() and any other symbols that must be callable from within Jinja templates.

 ### Naming convention
 The only strict requirement is that all templates to be used by automatic type-to-template mapping in the gen() function, must be within the same subdirectory and must be named according to the naming conventioned mentioned before.
 
-Templates can be stored in the sub-directories of the ifex/templates/ directory.
+Templates can be stored in the sub-directories of the output_filters/templates/ directory.
 
 The intended target format (output format) is normally clear from the naming of the subdirectory.  E.g. "protobuf", or "D-Bus" or "ARXML" or other output format.
