 This trait defines the interface for a polynomial commitment scheme. It is recommended to use the schemes from this crate that implement the `PolynomialCommitment` trait
 (e.g. the [vanilla KZG scheme](./src/kzg10/mod.rs) does not implement this trait, but the [Marlin scheme](./src/marlin/mod.rs) which uses it under the hood, does).
