 * @details
 * This file defines the @ref estimators::mvue::MVUE_4 class, which
 * implements a Minimum Variance Unbiased Estimator (MVUE) for combining
 * four measurements.
 *
 * Each measurement is associated with a variance. The estimator combines
 * the measurements according to their variances, giving greater weight
 * to measurements with lower variance.
 *
 * The class is templated to support different numeric types such as
 * @c float and @c double.
 *
 * @tparam T Numeric data type used for the estimator calculations.
