Double-Down: A mixed-precision interface to Intel’s Embree

Double-down is a mixed-precision interface to Embree intended to enable particle tracking for scientific applications relying on double precision. Currently, any mesh readable by the Mesh Oriented datABase (MOAB) and organized for use with the Direct Accelerated Geometry Monte Carlo (DAGMC) toolkit.

Warning: Double-Down is under active development. The API is still undergoing changes.
