This class manages a list of search paths and helps to find and open application-bound resources (files). :param base: default value for :meth:`add_path` calls. :param opener: callable used to open resources. :param cachemode: controls which lookups are cached. One of 'all', 'found' or 'none'.
| Method | __init__ |

| Method | __iter__ |
Iterate over all existing files in all registered paths. |
| Method | add |
Add a new path to the list of search paths. Return False if the path does not exist. |
| Method | lookup |
Search for a resource and return an absolute file path, or `None`. |

Add a new path to the list of search paths. Return False if the path does not exist. :param path: The new search path. Relative paths are turned into an absolute and normalized form. If the path looks like a file (not ending in `/`), the filename is stripped off. :param base: Path used to absolutize relative search paths. Defaults to :attr:`base` which defaults to ``os.getcwd()``. :param index: Position within the list of search paths. Defaults to last index (appends to the list). The `base` parameter makes it easy to reference files installed along with a python module or package:: res.add_path('./resources/', __file__)
Search for a resource and return an absolute file path, or `None`. The :attr:`path` list is searched in order. The first match is returend. Symlinks are followed. The result is cached to speed up future lookups.
