Report a bug.

• What is the current behavior?
  The example in the README appears to be incorrect or outdated. The parse_rule_file does not appear to exist. If I attempt to use this function, Python raises an error: AttributeError: 'IgnoreParser' object has no attribute 'parse_rule_file'.

• **If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem
  Running Python in a directory with a .gitignore file:

>>> import igittigitt
>>> parser = igittigitt.IgnoreParser()
>>> parser.parse_rule_file(".gitignore")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'IgnoreParser' object has no attribute 'parse_rule_file'

• What is the expected behavior?
  I can't find any parse_rule_file function in the source code. Guessing parse_rule_files is the intended function to use.

>>> parser.parse_rule_files(pathlib.Path('/home/bitranox/project/'))

• What is the motivation / use case for changing the behavior?
  I spent way too long trying to get this inexistant function working, And I'd rather no one else ever has to go through the pain again.
