compose not including lib in/from base layer

[Charles Butler]

The following line is included in the base layer when composing a charm inhereting from layer: base

import sys
sys.path.append('lib')

However the lib directory doesn't appear to be constructed properly when composing

 ls ../composed/trusty/test
composer.yaml copyright hooks Makefile metadata.yaml reactive README.md requirements.txt tox.ini

to reproduce generate a composer.yaml with the following contents:

includes: ['layer:basic']

and a metadata.yaml with the following contents:

name: test
summary: test
maintainers:
    - test <email address hidden>
description: na
tags:
  - layer
subordinate: false

Tested on charm-tools 1.6.1 as well as TRUNK from the charm-tools bzr repository

Possible relevant output:

(.venv)charles@xps13:~/projects/work/layers/composed/trusty/test$ charm inspect
Inspect test
# layer:basic
# test
# composer
