My question here boils down to, "Is there a way to remove certain
characters from a string?"
Here, I'm trying to set the variable roman_input (the string's name)
equal to the string minus those characters, the 3 Ms. (being the first
three characters of the string, they would be roman_input[0],
roman_input[1], and roman_input[2].)
Setting the (new) string equal to the (old) string minus those three
characters will enable calculations on the string to keep running,
because I have this piece of code, and similar pieces nested in a loop.
