When creating the virtual model, we wanted to allow users to play around
with different motion patterns to see how the skeletal elements interacted with one another,
as they would with the physical model. Aaron wrote a linkage model that handled the physics
of motion and kinematics between bones given observed properties in the actual organisms.
then helped him expand upon the svgViewR package to include interpolation functionality so
that when users interact with different sliders, they can view different forms of movement
in the model. They can choose to play all motion types at once, or play them individually to
view breakdowns of the motion patterns.
