Getting Started with EasyMVC

I am starting to think that I will be using Tom Bray's EasyMVC for my Flex applications. I have downloaded Greg Knight's sample from his post on his blog. I am having a lot of trouble wrapping my head around what exactly each part is supposed to do. I believe I understand that the view is for all of the user interface. I am not sure where I am supposed to place my code for events, data queries, and all the other stuff that I have going on. This is all very new to me. I am currently just cramming all of my code into a single mxml file. As my applications are growing more complex, I realize that this is not a good idea. There is so much going on in that one file that I get lost in my own code, this is not good.
