Add util method for parsing args for options. This method takes an array and searches for any strings in that array beginning with a hyphen. If it encounters such a string it strips the leading punctuation from that string and puts it into a new array. After iterating the given array it returns a 2-tuple containing the new array of options sans leading punctuation and the original array minus those extracted options.
