Update stanncam methods to support method chaining

[bfrymire]

Fixes #79

[stann-co]

looks gtm, but let's merge it to a new minor version branch.
With this being a feature we could also simplify the creation of new stanncams. Like instead of having so many extra optional paramters, i'd favor not having those params, but just calling whatever you need to change afterwards in a chain

Makes sense to bundle it with more updates.
So now the question is, do we add getter and setter methods for every stanncam variable? That way there's not a mix of method chaining and dot accessors when creating the stanncam?

I guess that makes most sense. I feel a little conflicted since it might overcomplicate just getting a single variable with a dot accessor. But i don't know if there's any real cases where people actually do that now that i think about it. Plus this doesn't remove that ability i guess
