#1.2.0 - added confreg function to construct confidence regions jointPredictiveSample.  Fixed bug in create.pgrid when midpoint == TRUE.  Modified plot.pgrid to automatically
plot confidence regions from confreg function.  A major benefit is that this automatically takes into account the poly.grid function and plots the pixels in the correct places with pgrid$pgrid has few observations that the total grid of locations.

#1.1.2 - modified plot.pgrid so that is was insanely fast using the image function instead of manually plotting each pixel.
