Function monotonic_solver::solve_and_reduce_with_accelerator

pub fn solve_and_reduce_with_accelerator<T: Clone + PartialEq + Eq + Hash, A>(
    start: &[T],

    max_size: Option<usize>, 
    filter: &[T],

Solves and reduces the proof to those steps that are necessary.

Uses an accelerator constructor initalized from start and goal.
