Make Composer Manager a Soft-Dependency

It's not required for 8.x, or at least it isn't supposed to be.

Did you find it requiring composer manager when you installed the module?

Composer manager for 7.x is a hard requirement. You are using a custom Drupal installation based on Composer - which is cool. But that is an edge case. The module is developed to work on a default installation of Drupal 7.

I cannot commit this patch because it will break the installation of the module. Without the wrapper API and something to alert the user that it does not exist the module will not work - then no one is happy.

A better approach will be to use a hook_requirements so the module cannot be installed. I would be in favor of implementing the suggestion of this issue if the module is blocked from being used. A hook_requirements in the install phase the prohibits the installation of the module if the API wrapper class does not exist (class_exists()) will be the best solution. This way they can choose to use composer manager to load the dependency or load it via some other method. I can write this later today or tomorrow.

I pushed updates to 7.x-1.x-dev that have the hook_requirements change. I have tested this with a site that is using Composer Manager to load the dependencies. Can you test in your environment using the Drupal Composer Drupal Project?

Crap... this change broke my Travis builds. I will address those later. I relied on the .info to load composer-manager and pull in the API wrapper. Will have to force loading composer-manager before scripts are run in Travis.

Fixed the Travis builds. Back to green :-)
