Algorithm in method get_nearest_edge_points improved. Warnings were built in because found edge points may not actually lie on the edge nearest to the point.

Extra methods were added in order to indicate points which are representative for a shape - esp. for those with centroids outside of the actual shape

General functionality for handling vector data moved to vectorlib and extended with the help of external package delaynay-triangulation

Moving all code to new folder 'lmgeo' which is required there as so-called top-level package. Only setup.py remains in place.

Specification of exact version numbers replaced by more flexible one indicating minimum version, for the dependency resolver to have more possibilities.

Better exception handling for something that seems to sometimes fail (wrt. Dataset from Netcdf4 library)

Changes to allow for less strict testing of extent, 2D NetCDF rasters, smart searching of a unique value in a raster etc.

Some problems were solved; some properties were added to a base class; attempt to enable installation by means of pip
