    # This class provides an object for the "Flavor" of a server.  The Flavor can generally be taken as the server specification,
    # providing information on things like memory and disk space.
    #
    # The disk attribute is an integer representing the disk space in GB.  The memory attribute is an integer representing the RAM in MB.
    #
    # This is called from the get_flavor method on a OpenStack::Compute::Connection object, returns a OpenStack::Compute::Flavor object, and will likely not be called directly.
    #

    #   >> flavor.name
    #   => "256 server"
