Feature: Overlap Analysis

This new Processing algorithm calculates the area and percentage cover by which features from an input layer are overlapped by features from a selection of overlay layers. New attributes are added to the output layer reporting the total area of overlap and percentage of the input feature overlapped by each of the selected overlay layers.

This is quite a common GIS task request, yet is full of traps for inexperienced users, and the amount of manual data work usually done by users to calculate these figures can often lead to mistakes and inaccurate results. We want to make spatial analysis as easy and foolproof as possible, so we've added Overlap Analysis as an inbuilt tool which allows this task to be done in a single step without risk of human error.
