Allow for "|" tag operator and further refinements to changing "a" to "an" when necessary
Fixed comments, nothing major
Added group_quotes method (converts quotes to dynamic tokens) and beginnings of text parsing (for <text> tokens)
Removed extraneous print statements and changed <quote_index> to <quote-index>
Added ability to parse <quote> tokens
Tokens can be parsed recursively (i.e. <<quote-0>> becomes <"quote">)
finished parse_text to allow for <text> token. currently picks emotions at random and not based on their ratios
