Improvements to SimpleComponent

[Mike Reich]

One of the first pieces of feedback I've received is that the SimpleComponent is too complex (ironically), and is going to be hard to use for first-timers. The observation was that putting things in a config hash hides the possible values and abstracts out what is happening - you have to know both what to define and how it works behind the scenes.

The suggestion for improvement was to wrap most of the functionality in an easy to understand (and find) public API.  This makes it clear both how to accomplish a task and what the expected/required values are.

So, here's what I'd propose for the SimpleComponent.

Creating DataProviders

We define an API for specifying DataProviders:

$this->addDataProvider("someAlias", "\Some\Classname", array("apiKey" => "someKey"));

Or, possibly

$this->addDataProvider("someDP", "\Some\Classname");

$this->someDP->apiKey = "SomeKey";

Accessing DataProviders

DataProviders become class instance variables.  So, to access a DataProvider, you use the $this-> syntax:

$this->someDP->process("do something with this text");

Creating Routes

Same would go for routes:

$this->addRoute("index");

or 

$this->addRoute("index", "someFunc");

Binding to DataProvider Events

Same approach:

$this->bindEvent("someDP", "load", function() {

  ....

});

I'm less sure about this one - might be a good idea to leave it as: $this->someDP->bind("load", function() {...});

Thoughts?
