Refine input

[afoster28]

• Create easy-to-use API: using the class, adding options, resetting the portfolio, retrieving variance
• Check API aligns with official input data provided

[secoman]

This version will allow users to input option parameters in the format optType, dir, K, T, Q and use default values for the Spot Price (S), Risk-free Interest Rate (r), and Volatility (sigma)

In this program:

• The user is prompted to enter the parameters for each option in the specified format (optType, dir, K, T, Q).

• The parameters are read and used to create a BlackScholes object with the default values for S, r, and sigma.

• The created BlackScholes object is added to the Portfolio.

• The user can enter as many options as desired and type exit to finish inputting data.

• After exiting the input loop, the program calculates and displays the variance of the portfolio.

Here goes the code:
