This class is similar to RegexpMatcher, but stores the regular expressions to match and ignore in files. For example, this class can be used for URL filtering. The matcher itself stores only the paths and the filenames to the lists. The file is automatically monitored and reloaded when it is modified. Searches are case-insensitive.
