A simple example

Let's start with a simple circuit, to introduce you to the common APIs and how they are used. The circuit will take a public input c, and will prove knowledge of two private inputs a and b such that

a \cdot b = c.

# extern crate halo2;
use halo2::arithmetic::FieldExt;

struct MyCircuit<F: FieldExt> {
    a: F,
    b: F,
}
