* \brief Matches strings using a series of include and exclude glob patterns.
*
* This string matcher class uses a sequential, ordered list of glob patterns to
* determine whether a string matches. Attached to each pattern is an include/exclude
* action. The patterns in the list effectively form a Boolean expression. Includes
* act as an OR operator while excludes act as an AND NOT operator.
*
* Examples (plus prefix is include, minus prefix is exclude):
* - +foo: foo
* - -foo: !foo
* - +foo, +bar: foo || bar
* - +foo, -bar: foo && !bar
* - +foo, -bar, +baz: foo && !bar || baz
*
* The only reason for inheriting from GlobMatcher is so we can access the protected
* globMatch() method.
