Instance Public methods
This method will fetch the field value by header. It has the
same behavior as Hash#fetch: if
there is a field with the given header, its value is returned.
Otherwise, if a block is given, it is yielded the header and
its result is returned; if a default is given as the second
argument, it is returned; otherwise a KeyError is raised.
