added the concept of zero into monadic such that objects which mixin
monadic now have the ability to identify their own zeroes. The idea
behind this design comes from ORMs especially stuff like ActiveRecord
which still returns nils despite the fact we call find and whatnot
on things with specific classes. Objects which support their own
zeroes will generally make things work easier as it avoids the problem
of having to check object class and rely on whiny nils.

added the nothing? function to the example context and made it so that you can now initialize a context without an object
