demu: Optimal Design Emulators via Point Processes

Implements the Determinantal point process (DPP) based optimal design emulator described in Pratola, Lin and Craigmile (2018) <arxiv:1804.02089> for Gaussian process regression models. See <http://www.matthewpratola.com/software> for more information and examples.
