A function that calculates the average slope over a tooth
or some other 3D surface

Surface topography calculations of Dirichlet's normal energy,
relief index, surface slope, and orientation patch count for teeth using scans of
enamel caps.
Importantly, for the relief index and orientation patch count calculations to
work, the scanned tooth files must be oriented with the occlusal plane parallel
to the x and y axes, and perpendicular to the z axis. The files should also be
simplified, and smoothed in some other software prior to uploading into R.
