Methods for anonymizing data for public distribution

This QGIS Processing provider plugin implements different methods for the
anonymization of spatial data (typically point samples) with the goal of making
the data publicly available, while preserving the privacy of the individuals
whose information the dataset contains (see [3]).
The differential privacy algorithm is based on the algorithm outlined in [1]
and implemented by Konstantinos Chatzikokolakis in the Location Guard
browser extension [2]. The grid based masking system is discussed in [4].
