Function translate_inputs 

pub fn translate_inputs<T, U>(circuit: Circuit<T>, trans: &[U]) -> Circuit<T>
where
    T: Clone + Copy + Ord + PartialEq + Eq + Default + TryFrom<usize> + TryFrom<U>,
    <T as TryFrom<usize>>::Error: Debug,

Translates circuit inputs using translation table.

A trans is translation table. In this table entry index is original circuit input index and table entry value is destination circuit input index. Function returns circuit with translated inputs.
