Replace the specified outNumChars characters starting at the specified outPosition in this string (or the suffix of this string starting at outPosition if outPosition + outNumChars > length()) with the specified initial numChars characters in the specified characterString. Return a reference providing modifiable access to this string. Throw out_of_range if outPosition > length(). The behavior is undefined unless characterString is at least numChars long.
