Consider storings 'parameters' on objects, including algorithms and projects

[jgostick]

It might be handy to have a parameters attr on all objects to store constant things. This could be really neat if a 'search' is conducted upstream on higher objects if the value is not found on self, like:

alg.parameters['j0'] -> project.parameter['j0']

This would allow globals constants to be defined, but also enable over-riding if necessary.

On the other hand, this does add some 'behind the scenes' magic which tends to be confusing.

The new Base class will allow for a param prefix, so param.k etc can be stored on any object.
