module Spider
# Utility that makes the including Hash accept a dotted syntax for keys.
# The dotted syntax can be used to access and create on the fly sub-hashes.
# Example:
# h = MultiLevelHash.new
# h['one.two.three'] = 'some val'
# p h => {'one' => {'two' => {'three' => 'some val'}}}
# p h['one.two.three'] => 'some val'
# p h['four.five'] => nil
