New package "geotools"

Dear All,

I have upload a new package "geotools", that main purpose is to
propose functions to get distance between cities, with city name or
postal code (usage: shipment).

For now: there is only the french cities dataset.

An example:
Return all postal code at 7 kms from Paris:
codesNearToCode(zipCode("Paris"),7)


Regards,

Antoine Lucas.
