Constrained Phenotypic Selection Indices (Chapter 3)

Description

Implements constrained phenotypic selection index methods from Chapter 3. These methods allow breeders to impose restrictions on genetic gains or specify target gains while maintaining selection efficiency.

Methods included: - Restricted Linear Phenotypic Selection Index (RLPSI) - Kempthorne & Nordskog (1959) - Predetermined Proportional Gains (PPG-LPSI) - Tallis (1962) - Desired Gains Index (DG-LPSI) - Pesek & Baker (1969)

All implementations use C++ primitives for mathematical operations.
