Immutable Sample

[treyshaffer]

As the Sample is being treated as an immutable struct, you could use a Builder to make it immutable and then have instance data publicly accessible. It seems this class is just being treated as a container for data.

Note: This will change instantiation and data accessing.

Hi @BlurryZombie I appreciate your effort in this PR but I prefer not to merge it.
I understand this change would make the code base of Sample object better but the main target of this project is illustrate how to do animations. So in order to keep things simple and easy to understand I don't mind scarifying code correctness.

That said, if you like to contribute with more Android animation examples I'm very happy to add those.

Yeah, I understand. thanks for the reply :)
