I believe the plan was something like:

* Give each stage a public Initialize(boost::property_tree::ptree& tree) method that each stage's constructor can choose to call or not in its ctors
* Give each stage a public ValidateOptions() method that throws libpc::validation_errors if something isn't right.
* Give each stage a public boost::property_tree::ptree GetDefaultOptions() that fills out a default tree that the user can then tweak values of and set on Initialize

I'm not sure this is the way to go even though I lean this way...
