Examples from Josh Suereth's SBT Cookbook

There's currently an issue with global plugins + source dependencies. It's classpath related. Mark is looking into it, but we're pushing for that fix before we start really pushing source dependencies. Here is the error:

[error] AttributeKey ID collisions detected for: 'defaults' (np.Defaults, np.Defaults)
[error] Use 'last' for the full log.

If you have installed np as a global plugin, comment it out so the build can run, at least until we get a fix in place.
