bee98999db Make Function clone.
To achieve this, the function type wrapped by Function was changed to remove the `Box`.

9fc86a934f Change context trait.
Instead of one catchall trait for contexts, there are now several:

 * `Context` is now a "use-only" context, allowing only to retrieve variable names and call functions.
 * `ContextWithMutableVariables` also allows to mutate variables.
 * `ContextWithMutableFunctions` also allows to mutate functions. However this is not used anywhere at the moment. It will come in handy when the evalexpr language gets a function definition feature.
 * `GetFunctionContext` also allows to retrieve functions as `Function` type. This is uncommented at the moment, as it does not have any use in the crate as of now, and likely also not with planned future features.

 Additionally, this commit makes functions generic over the context type, as opposed to having a dynamic reference to a context type.

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.

e328adb97b Implement Node::iter_identifiers()
This commit implements an iterator over the identifiers in an expression.
The identifiers are iterated pre-order, meaning that higher nodes in the tree are emitted first.
The identifier iterator is based on a general iterator over all nodes in an operator tree, which can be used for further featues.
