/*
PSEUDOCODE:
1. Make variables happen
2. Main loop starts
    a. Display menu
    b. start another loop with a switch statement that checks input as well as makes an option selection
    c. set the "answer" variable to the basefee static double (this helps us with our calculations and the main loop looping)
    d. calculate how the membership adds up over 10 years with a for loop and display it
    e. set some variables back to their default values and loop it back again
    f. make some whitespace
