		Using the API Annotations available from GHC 7.10.2, this
		library provides a means to round trip any code that can
		be compiled by GHC, currently excluding lhs files.
		
		It does this with a phased approach
		
		* Delta - converts GHC API Annotations into relative
		offsets, indexed by SrcSpan
		
		* Transform - functions to facilitate changes to
		the AST, adjusting the annotations generated in the
		Delta phase to suit the changes.
		
		* Print - converts an AST and its annotations to
		properly formatted source text.
		
		* Pretty - adds annotations to an AST (fragment) so that
		the output can be parsed back to the same AST.
		
		
		Note: requires GHC 7.10.2 or later
