Baseball examples and doc updates

* Adds a new Examples project with a small set of Models and Tasks with baseball as the subject matter.
* Changes README to use examples from new project
* Removes the TDD section from the README (not worth the extra bulk in README since in my opinion)
* Other README updates for whitespace, clarity (hopefully), etc.

>The README diff is difficult to look at because of all the whitespace changes - sorry.

Tasks
