PiAlgorithm class abstract

Abstract base class for algorithms that compute the value of pi.

This class defines the common properties and methods for algorithms that calculate the value of pi to a specified number of digits. Subclasses must implement the calculate() method to provide the specific algorithm for computing pi.
