  - Added validation checks to ensure integer-valued inputs.

                 Changes in version 0.1.1 (2026-03-23)                  

  - Optimized closedCI() using vectorized matrix operations for
    significantly faster performance.
  - Added correction to remove excess decimal value from adjusted
    Schumacher-Eschmeyer estimator.
