If several objects are provided, a list of rasters is returned
To obtain this modified UD raster from a DBBMMBurstStack
object, transform the object with the UDStack function into a '.UDStack' class, and than use the getVolumeUD
function upon the obtained object.

getVolumeUD(leroydbbmm) # for a DBBMM object
getVolumeUD(dbbmmstack) # for a DBBMMStack object
getVolumeUD(leroydbgb) # for a dynBGB object
getVolumeUD(leroydbbmm, leroydbgb) # for several objects
plot(getVolumeUD(leroydbbmm))
## e.g. select the raster corresponding to the 95% UD
leroyUD <- getVolumeUD(leroydbbmm)
leroyUD[leroyUD>0.95] <- NA
plot(leroyUD)
