Move aliases and checkpoints folders to steps
Use ProxyCommand to improve the debian7-g5k recipe
Fixed #2: Removed recipe_path and workspace.

The concept of workspace is not interesting if kameleon takes as
arguments the full path of the recipe YAML. kameleon simply uses a
WORKDIR, which is the current directory in all cases
Added a breakpoint.yaml step to make the breakpoint in the recipe directly
Some optimizations of recipes
Make a safe copy with kameleon new command #11
Added a simple extend recipe feature #11
removed unused recipes
Show diff between user recipe and template #11
Don't log identifier of microstep during build process
removed my g5k username
Fixed log debug
Copied base recipe with extend #11
refactor all recipes with the "extend" feature #11
Removed unused recipe metainfo #11
Revert 6e76eb7
introduce the keyword "@base" in the extended recipes... #11

To manage more precisely recipes inheritance

extend: ubuntu-14.04

bootstrap:
- @base

setup:
- before_custom_step:
    - pull_image:
      - exec_in: docker pull ubuntu:trusty
- @base
- create_user:
    - name: sharrache
    - groups: sudo,admin

export:
Add ERB template that will be used by extended recipes #11
Sorted the templates list
Added kameleon import subcommand #11
