Search cities matching a given criteria

Hi,

a while ago I needed text completion for a field where user would input a city name. I didn't find anything so simple on HERE's API and then decided to implement it myself.

I formatted the code to follow the standards of the project and was wondering if it would be an interesting extension. What do you think?

What it does is to do a basic search with the given query, filter for the "city-town-village" category ID and, finally, geocode each filtered entry.

Something interesting that could be added is the option to search for any kind of place with a given category ID.

Thanks
