Detailed Description

template<typename GOAL_TYPE, typename CANDIDATE_TYPE>
class best_match< GOAL_TYPE, CANDIDATE_TYPE >
A type for use when determining the best match against a string,
expressed as a template so that we can match against various
string-like types (const char *, frontend identifiers, and preprocessor
macros).

This type accumulates the best possible match against GOAL_TYPE for
a sequence of elements of CANDIDATE_TYPE, whilst minimizing the
number of calls to get_edit_distance and to
edit_distance_traits<T>::get_length.
