URL: https://github.com/apache/commons-numbers/pull/111

   This PR refactors Complex class using functional interfaces and static methods. 
   This allows reuse of the refactored static functions for Operations on List/Matrices of Complex Numbers (NUMBERS-186)
   
   The changes retain binary backward compatibility.
   
   Summary of changes
   
   1) Introduced following interfaces  for Complex Number Operations
    DComplex - interface representing a complex number with double precision in cartesian form
    DComplexUnaryOperator - unary operations on DComplex
    DComplexBinaryOperator - binary operations on DComplex
    DComplexScalarFunction -  operations on a DComplex and double type returning a DComplex type
    DComplexConstructor - interface to create the DComplex result object from real and imaginary parts
   
   2) Refactored instance methods of Complex class as static functions in ComplexFunctions and ComplexBiFunctions
   The static functions use the functional interface signatures described above
   
   3) Added default methods on functional interfaces to compose Complex operations.
