getArea

Extracts the polygon area for an rKIN object for each group and level.

Applies methods used to estimate animal homerange, but
instead of geospatial coordinates, we use isotopic coordinates. The estimation
methods include: 1) 2-dimensional bivariate normal kernel utilization density
estimator, 2) bivariate normal ellipse estimator, and 3) minimum convex polygon
estimator, all applied to stable isotope data. Additionally, functions to
determine niche area, polygon overlap between groups and levels (confidence
contours) and plotting capabilities.
