Functions
Array	hmap::abs (const Array &array)
	Absolute value.
Array	hmap::abs_smooth (const Array &array, float mu)
	This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
Array	hmap::abs_smooth (const Array &array, float mu, float vshift)
	This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
