//! Generic Genetic Programming framework routines
//!
//! This crate supplies a generic framework for solving GP programs.
//! As a consumer, you'll need to supply the following:
//!
//! - Enums to encode the various AST node types.
//! - Implementations of `AstNode`, `Mutatable` and `RandNode` traits
//!   (which can usually be autogenerated using `impl_astnode!()`).
//! - A fitness function evaluating the success of a given program.
//!
//! Create `random_population` from your types, then call `evolve` repeatedly to
//! improve the fitness of the population.
//!
//! For a working example, see the `santa_fe_ant` in the `examples/` directory.
