Function isIdentity

isIdentity<T>(
    struc: ChalkboardStructure<T>,
    element: T,
    type?: "add" | "mul",
): boolean
Checks if an element is the identity of an algebraic structure.
Type Parameters
- T
Parameters
- struc: ChalkboardStructure<T>
  The algebraic structure
- element: T
  The element
- Optionaltype: "add" | "mul" = "add"
  The type of identity to check ("add" for additive identity, "mul" for multiplicative identity, defaults to "add")
Returns boolean
Example
```
const Z4 = Chalkboard.abal.group(Chalkboard.abal.Z(4), (a, b) => (a + b) % 4, 0, (a) => (4 - a) % 4);
const valid = Chalkboard.abal.isIdentity(Z4, 0); // Returns true
```
