Feature: Fuzzy Logic - Fuzzfiy Raster (gaussian membership)

The Fuzzify raster (gaussian membership) algorithm is a native implementation of a fuzzy logic algorithm. It transforms an input raster to a fuzzified raster and thereby assigns values between 0 and 1 following the 'gaussian' fuzzy membership function. The value of 0 implies no membership with the defined fuzzy set, a value of 1 depicts full membership. In between, the degree of membership of raster values follows the 'gaussian' membership function. The gaussian function is constructed using two user-defined input values which set the midpoint of the gaussian function (midpoint, results to 1) and a predefined function spread which controls the function spread.
