Pull Request Overview
This PR implements the scattering ISO calculation functionality based on ISO 17497-1:2004, adding functions to calculate diffuse scattering coefficients and related parameters.
- Adds a new
diffusemodule with functions for maximum absorption coefficient, baseplate scattering coefficient, and main calculation logic - Implements comprehensive test coverage for the new functions
- Updates documentation structure to include the new scattering module

imkar/scattering/diffuse.py:95
- The function name 'calculation' is too generic and unclear. Consider a more descriptive name like 'calculate_scattering_coefficients' or 'diffuse_scattering_calculation'.

tests/test_scattering_diffuse.py:68
- The test function name suggests it tests negative N values, but the test actually uses N=5 (positive). The function name should be corrected to match what it actually tests.
def test_maximum_baseplate_scattering_coefficient_negative_N():
imkar/scattering/diffuse.py:95
- The main calculation function lacks test coverage. This is critical functionality that should have comprehensive tests to verify the mathematical calculations and edge cases.

The function lacks input validation for the parameters. Consider adding checks for valid ranges, data types, and array shapes to prevent unexpected behavior.

The comment is misleading as the test uses a positive value (N=5). The comment should be updated to reflect the actual test behavior.
Suggested change
| # Negative N is technically an integer, but let's check if it works | |
| # Test the function with a positive integer value for N (e.g., N = 5) |
