Flexible recursive directory iterator: scandir meets glob("**", recursive=True)

 Recursive directory iterator supporting:
 .
  * flexible filtering including wildcard path matching
  * in memory representation of file-tree (for repeated access)
  * efficient access to directory entry properties (`posix.DirEntry` interface)
    extended with real path and path relative to the recursion root directory
  * detection and handling of cyclic symlinks
 .
 This package installs the library for Python 3.
