Optimized the transition() function for 4 and 8
directions with user-defined functions. Run time is reduced by 10+%, and
the peak memory consumption is massively reduced.
Updated deprecated usage of the Matrix library.
Added unit tests for the transition() function.
Add workaround (fix?) for pathInc() code in Overview
vignette.

BUG FIXES
Fix transition with Mahalanobis distance method use
x.minus.y <- raster::getValues(x)[adj[,1],] - raster::getValues(x)[adj[,2],]
instead of
x.minus.y <- xy[adj[,1],-1]-xy[adj[,2],-1]
