+/// Defines wrappers around types.
+///
+/// For example, the macro invocation seen below:
+///
+/// ```rust,ignore
+/// define_wrapper_type!(CaseId => usize);
+/// ```
+///
+/// Would define a wrapper type that looks like the following:
+///
+/// ```rust,ignore
+/// pub struct CaseId(usize);
+/// ```
+///
+/// And would also implement a number of methods on this type making it easier
+/// to use.
+///
+/// These wrapper types become very useful as they make the code a lot easier
+/// to read.
+///
+/// Take the following as an example:
+///
+/// ```rust,ignore
+/// struct State {
+///     contracts: HashMap<usize, HashMap<String, Vec<u8>>>
+/// }
+/// ```
+///
+/// In the above code it's hard to understand what the various types refer to or
+/// what to expect them to contain.
+///
+/// With these wrapper types we're able to create code that's self-documenting
+/// in that the types tell us what the code is referring to. The above code is
+/// transformed into
+///
+/// ```rust,ignore
+/// struct State {
