Builds the Convex Hull of the features of a layer
Convex hull is a polygonal area that is of smallest length and so that any pair of points within the area have the line segment between them contained entirely inside the area.

Defining the convex Hull of a set of points is useful, for example in the case of enclosing the points, using a fence of shortest total length.

While in general the Convex Hull is good to describe the shape of the input data points, in many cases a polygon that describes better the region occupied by the point cloud is needed. See the Create Concave Hull function
