-# The "fuzzy" file finder provides a way for searching a directory
-# tree with only a partial name. This is similar to the "cmd-T"
-# feature in TextMate (http://macromates.com).
-# 
-# Usage:
-# 
-#   finder = FuzzyFileFinder.new
-#   finder.search("app/blogcon") do |match|
-#     puts match[:highlighted_path]
-#   end
-#
-# In the above example, all files matching "app/blogcon" will be
-# yielded to the block. The given pattern is reduced to a regular
-# expression internally, so that any file that contains those
-# characters in that order (even if there are other characters
-# in between) will match.
-# 
-# In other words, "app/blogcon" would match any of the following
-# (parenthesized strings indicate how the match was made):
-# 
-# * (app)/controllers/(blog)_(con)troller.rb
-# * lib/c(ap)_(p)ool/(bl)ue_(o)r_(g)reen_(co)loratio(n)
-# * test/(app)/(blog)_(con)troller_test.rb
-#
-# And so forth.
