How can code be more modular/componentized?

[marknutter]

Right now the two examples just have one big reducer file with all the reducer functions, and at most two files for vDom objects. A way to make the code more modular and component based should be determined.

Made some headway on this question in #19 but there's probably more that can be done. Some experimentation around how to reuse components and extend them.
