Make names consistent with Scala style guide

[ghost]

From Scala style guide:

Textual (alphabetic) names for methods should be in the camelCase style with the first letter lower-case

[jsuereth]

In this case, I'm going to disagree with the style guide.

The method we have is similar to the following:

object DoStuff {
  def apply(...)....
}

In code you still write DoStuff(...). I understand it's a general convention, but most factories are capitalized, hence I'm mimicking that to cause less confusion about what's happening.

In any case, if it helps, that method will go away once AutoPlugins are introduced in chapter 11.

Thanks for answer.
