		# KeenQuotes

		-A lightweight natural language parser that converts straight quotes
		-to curly quotes.
		+A lightweight natural language parser for converting straight quotes
		+into curly quotes.
		+
		+# Algorithm
		+
		+The overall algorithm follows:
		+
		+1. Run a lexer to produce relevant lexemes (e.g., words, numbers, and periods).
		+1. Add lexemes to a 3-element circular queue, capturing either side of a
		+straight quote.
		+1. Tokenize all unambiguous single/double quotes, primes, and apostrophes.
		+1. Resolve as many ambiguous quotation marks as possible.
		+1. Emit unresolved conversions.
		+
		+See the Lexer and Parser classes for details.
