Interface that must be implemented by all plugins.
Only objects which implement this interface will be considered for return
by C{getPlugins}. To be useful, plugins should also implement some other
application-specific interface.

A collection of L{CachedPlugin} instances from a particular module in a
plugin package.
@type moduleName: C{str}
@ivar moduleName: The fully qualified name of the plugin module this
represents.
@type description: C{str} or C{NoneType}
@ivar description: A brief explanation of this collection of plugins
(probably the plugin module's docstring).
@type plugins: C{list}
@ivar plugins: The L{CachedPlugin} instances which were loaded from this
dropin.

Compute all the possible loadable plugins, while loading as few as
possible and hitting the filesystem as little as possible.
@param module: a Python module object. This represents a package to search
for plugins.
@return: a dictionary mapping module names to L{CachedDropin} instances.

Retrieve all plugins implementing the given interface beneath the given module.
@param interface: An interface class. Only plugins which implement this
interface will be returned.
@param package: A package beneath which plugins are installed. For
most uses, the default value is correct.
@return: An iterator of plugins.

Return a list of additional directories which should be searched for
modules to be included as part of the named plugin package.
@type name: C{str}
@param name: The fully-qualified Python name of a plugin package, eg
C{'twisted.plugins'}.
@rtype: C{list} of C{str}
@return: The absolute paths to other directories which may contain plugin
modules for the named plugin package.
