More testing and small fixes
* Testing found that if attribute is not in shapefile NPE would occur
* Also, geometries were coming through as multilinestrings
* adding transects that are resulting from and used in test
* adding intersections resulting from test
* Ignoring tests because it takes a really long time
Example block code for R
* written as test so it is easy to run
* eventually some of this code will make its way into real code
