Functions
Array	hmap::local_max (const Array &array, int ir)
	Return the local maxima based on a maximum filter with a square kernel.
Array	hmap::local_median_deviation (const Array &array, int ir)
	Computes the local median deviation of a 2D array.
Array	hmap::local_min (const Array &array, int ir)
	Return the local minima based on a maximum filter with a square kernel.
Array	hmap::local_mean (const Array &array, int ir)
	Return the local mean based on a mean filter with a square kernel.
Array	hmap::relative_elevation (const Array &array, int ir)
	Calculates the relative elevation within a specified radius, helping to identify local highs and lows.
Array	hmap::ruggedness (const Array &array, int ir)
	Computes the ruggedness of each element in the input array.
Array	hmap::rugosity (const Array &z, int ir, bool convex=true)
