#
# Following PEP 302, this method checks if this importer applies to
# this package/module. When python goes to import, it will loop through
# the importers of sys.meta_path in order and use the first one that
# returns True to load the module. If none return True, it falls back to
# the built-in importer.
#
# For example, if a piece of python code has:
#
# from java.util import ArrayList
#
# that will pseudo-translate to:
#
# if JavaImporterInstance.find_module("java"):
# if JavaImporterInstance.find_module("java.util"):
# JavaImporterInstance.load_module("java.util.ArrayList")
#
# For a python module, this method should ideally always return False so
# that python will fall back to its built-in importer.
