GRK bug

GRK throws error when called through the factory pattern

from hypertiling import HyperbolicTiling
T = HyperbolicTiling(7, 3, 5, kernel="GRK")

but works in this case:

from hypertiling.generative.reflectionkernel import KernelGenerativeReflection
T = KernelGenerativeReflection(7,3,3)

can you reproduce that @ythurn
