Added incremental acceptance rate report to oli_nested output.

Now print acceptance rate as simulation goes along.

Added ability to convert spin angles, some C99-related build changes.

Moved to_array and from_array to parameters.ml.

Added _tags file (left out by mistake).

Added -nlive option.

Added OCaml global lock release and acquire so likelihood computations can run in parallel.

Added header printing for posterior.dat.

Added spinning parameters (not tested injection recovery yet).

Changed time parameterization to be t = 0 at trigtime, check for out-of-bounds parameters before calling log(L).

Oli_nested compiles, but seg faults.

Checked consistent log(L) between LI and OCamlLALInference.

Initial import---likelihood is probably working now.
