+\brief Class representing the geometry of a capsule.
+
+Capsules are shaped as the union of a cylinder of length 2 * halfHeight and with the 
+given radius centered at the origin and extending along the x axis, and two hemispherical ends.
+\note The scaling of the capsule is expected to be baked into these values, there is no additional scaling parameter.
+
+The function PxTransformFromSegment is a helper for generating an appropriate transform for the capsule from the capsule's interior line segment.
