"""Support for simplified access to data on nodes of type omni.graph.tutorials.OverrideType

This is a tutorial node. It has an input and output of type float[3], an input and output of type double[3], and a type override
specification that lets the node use Carbonite types for the generated data on the float[3] attributes only. Ordinarily all
of the types would be defined in a seperate configuration file so that it can be shared for a project. In that case the type
definition build flag would also be used so that this information does not have to be embedded in every .ogn file in the
project. It is placed directly in the file here solely for instructional purposes.  The compute is just a rotation of components
from x->y, y->z, and z->x, for each input type.
