Function emulation using Gaussian processes

tremulator provides the Emulator class for easy emulation of expensive functions with user-defined training and acquisition functions. It is built upon george and allows the trained emulator to be saved to an asdf file. The saved file can be read by the Interpolator class which then requires no more training.

Important note: loading a file requires this forked version of george, since otherwise the kernel cannot be instantiated correctly. This installation should happen automatically when installing through Github.
