Permanent

All Implemented Interfaces:
```
public final class Permanent
extends PermSolver
                    
```
Implementation of the MATLAB perm.m permanent computation algorithm.
This implementation mirrors the MATLAB perm.m function which computes the permanent of a matrix by applying computational savings when some rows or columns are repeated. It uses the inclusion-exclusion principle with multiplicities to efficiently handle matrices with duplicate rows or columns.
The algorithm:
- Detects and counts repeated columns/rows
- Uses inclusion-exclusion with multinomial coefficients
- Applies pprod iterator for generating all combinations

 Unit compute()
```
    Compute the permanent or approximation for the given matrix. This method must be implemented by all concrete solver classes. The result should be stored in the value property.
