'''
pokemon.py -- a hangoutsbot plugin for retrieving information about pokemon, given a name
This uses the pokeapi.co API to retrieve the information.
Because Pokéapi limits requests to 300 requests per resource, we store cached data for each Pokémon for 5 days - this should be sufficient for up to 1500 Pokémon overall. Currently there are approximately 811 Pokémon accessible through the Pokéapi so this should be more than enough. Of course, the API limit is per resource so theoretically no caching is required, but let's be API-friendly.
