Fri, 3 August	in progress	start writing the transformations from CS ASTs to JS ASTs
	in progress	start pulling in the test suite from jashkenas/coffee-script
		use Mozilla’s source map generator to generate source maps
		finish up cscodegen
		finish writing the transformations from CS ASTs to JS ASTs
		self-host
		enhance escodegen to accept a grammar for generating CSTs
		expand the language and include all the features we initially left out
		start using it to compile popular projects; see if they continue to pass their test suites
		pass the current CS compiler’s entire test suite
		documentation
