Added Tiling of Input Layers

By adding the tiling function Flow-Py needs less RAM for it's computations. This gets important when runing it on whole countries or states.
Make sure that you have enough Hard Drive space avaiable for the saved tiles. They are stored in the temp folder under res_... and can be deleted after the calculation is finished.

Flow-Py: routing and stopping of gravitational mass flows

Flow-Py is an open source gravitational mass flows (GMFs) run out model. The main objective of this tool is to compute the spatial extent of GMFs, which consists of the track/path and deposition areas of GMFs in three dimensional terrain. The resulting run out is mainly dependent by the terrain and the location of the starting/release point. No temporal equations are solved in the model. Flow-py uses existing statistical-data-based approaches for solving the routing and stopping of GMFs.

This tool has been designed to be computationally light, allowing it application on a regional scale. This tool is written in python and takes advantage of pythons object oriented class structure. The organization of the tool allows users to address specific GMF research questions by keeping the parameterization flexible and the ability to include custom model extensions/ad-ons.
