Generates a minimum convex polygon (MCP; i.e., convex hull) that
is delineated from occurrence locality coordinates.
This function is a wrapper for `chull()` that makes a SpatialPolygons object.

Facilitates workflows to reproducibly transform estimates of
species’ distributions into metrics relevant for conservation. For
example, combining predictions from species distribution models with other
maps of environmental data to characterize the proportion of a species’
range that is under protection, calculating metrics used under the
International Union for Conservation of Nature (IUCN) Criteria A and B
guidelines (Area of Occupancy and Extent of Occurrence), and calculating
more general metrics such as taxonomic and phylogenetic diversity, as well
as endemism. Also facilitates temporal comparisons among biodiversity
metrics to inform efforts towards complementarity and consideration of
future scenarios in conservation decisions. 'changeRangeR' also provides
tools to determine the effects of modeling decisions through sensitivity
tests.
