6ace829117 Create mutable context when using eval functions without context 
While this is a tiny hit on performance, it is something that the user probably wants.
It specifically prevents the user from seeing ContextNotManipulable errors when using the full power of evalexpr in the simplest eval calls.

Implements #45

e6c19077b6 Implement value decomposition API 
* Removed expect_... methods and replaced them with .as_...() methods. This removes the need to import the free-standing methods every time and makes the code cleaner.
 * Changed all the examples appropriately.

Implements #53
