wrote a optimized cython version for holt winters: 100x speedup
added a class for the optimization, which stores the arrays. also added a optimized version for the mse
add global optimum estimation with 10000 hw calculations
use lbfgs optimization to find local optimum
automatic building and import into the forecasting classes. yeah :)
updated parameters tool
fixed numpy warning in code. made build_extension use logger. should be ready to use now
