The documentation currently states that Inversion of Control (IoC) and
Dependency Injection (DI) are the same thing. Although the two terms
are related, they are not synonymous: DI is a type of IoC.
I believe this change is important because using the terms
interchangeably really muddies the water about the meaning of these two
fundamental concepts of software frameworks.
