Detailed Description

The manager of plugins.

The plugin manager is responsible for loading the plugins (via PluginLoaders) and retains ownership of the Plugin objects.

Each plugin has a numeric ID associated with it. The plugin IDs can be found in common/protocol/Ola.proto

Plugins can be disabled through the preferences file. Some plugins may conflict with others, in this case the first plugin will be started and the rest of the conflicting plugins are ignored.

Plugins are active if they weren't disabled, there were no conflicts that prevented them from loading, and the call to Start() was successfull.
