"""
Translation rules for Valencia Community road network.

This is so simple that it'll be used as an example of how to build translation methods.

The important thing is that a file like this must define a "translateAttributes" function that, taking a directory of attributes (key:value), will return a directory of tags (key:value)

The function must allow for empty directories.

The reason for using a full module is that you can define auxiliary functions and data structures here. But this example is so simple it won't have any auxiliary stuff at all.
