I’m still learning about the Rails opinion on where stuff belongs.  
Can someone explain to me the difference between code in the lib vs.  
code in a plugin. What scenarios are appropriate for each approach?

Plugin is _usually_ supposed to be 3rd party generic code.

lib is for your own application specific supportive libraries.
