Integrate Alive with DI containers for object instantiation

[Ijwu]

Consider integrating the use of various dependency injection libs to allow Alive to instantiate objects with bindings in the DI container.

Libraries to consider are:

• Ninject
• CastleWindsor
• Unity

I believe those may be the most used or popular DI libraries.

This is a very interesting idea. It's been also requested in #105. I will research DI and how we can bring support to various libraries.
