Overview

Public: Represents a place and knows how to convert it to param.

Examples

GoogleDistanceMatrix::Place.new address: "My address"

You may also build places by other objects responding to lat and lng or address.
If your object responds to all of the attributes we'll use lat and lng as data
for the Place.
