stats() function in rasdaman

[Dimitar Misev]

gdalinfo has a -stats option which computes min, max, mean, stddev.

It doesn't hurt to have something similar in rasdaman for getting some quick idea about the data. The result of stats() could be encoded as a struct of floats.

E.g.

$ rasql -q 'select stats(c) from lena as c' --out string

Output (max, min, mean, stddev, …)

  Result element 1: { 249, 12, 108.83, 50.14, ...}
