+/// Specialized YAMLIO scalar type for representing a binary blob.
+///
+/// A typical use case would be to represent the content of a section in a
+/// binary file.
+/// This class has custom YAMLIO traits for convenient reading and writing.
+/// It renders as a string of hex digits in a YAML file.
+/// For example, it might render as `DEADBEEFCAFEBABE` (YAML does not
+/// require the quotation marks, so for simplicity when outputting they are
+/// omitted).
+/// When reading, any string whose content is an even number of hex digits
+/// will be accepted.
+/// For example, all of the following are acceptable:
+/// `DEADBEEF`, `"DeADbEeF"`, `"\x44EADBEEF"` (Note: '\x44' == 'D')
+///
+/// A significant advantage of using this class is that it never allocates
+/// temporary strings or buffers for any of its functionality.
+///
+/// Example:
+///
+/// The YAML mapping:
+/// \code
+/// Foo: DEADBEEFCAFEBABE
+/// \endcode
+///
+/// Could be modeled in YAMLIO by the struct:
+/// \code
+/// struct FooHolder {
