+/**
+* @file types.h
+* @author Paul Oliver
+*
+* Declare main typedefs for the Salis library. Salis depends on fixed-width
+* unsigned types being available. We use the limits header to define these in
+* a C89 compliant way. Also, we typedef respective pointer types and a string
+* type to aid in header parsing.
