MoL Update
New integrator Euler. This is an explicit, first-order method, mostly
useful for debugging.
New integrators AB (Adams-Bashforth) with various orders. These are
explicit integrators using several past timelevels to provide
higher-order integration with a single RHS evaluation each.
Introduce LinearCombination, a generic routine to calculate linear
combinations of grid functions. This simplifies existing code, and can
be overloaded if MoL should run on a device (e.g. with OpenCL).
Replace cctk_lsh with cctk_ash where necessary.
