added API call is_sep() to parameters
cleanup to cmasolutions.cc
added support for surrogates with support for custom strategies. ACM strategy and Ranking SVM are included, ref #57
Merge branch 'dev' into surrogates
added visualization for surrogates, ref #57
use trick to deactivate median value stopping criteria which is fooled by ranks provided by the surrogate instead of proper objective function values, ref #57
fixed bug in check of tolX stopping criteria when using sep algorithm
moved convenience function set_str_algo from parameters to cmaparameters in order to set 'sep' flag while setting the algorithm
added surrogate support to 'sep' algorithms, ref #57
Merge branch 'master' into surrogates
support for external activation control of stopping criteria, ref #74
simple surrogate strategy now gets manual and automatic controllable surrogate lifelength. Automatic control still underoptimal, ref #57
added surrogate as feature in readme
Merge branch 'dev' into surrogates

Merge branch 'dev' into surrogates
surrogate strategy now works on top of any other strategy through template, closes #80
optimize() in eval/ask/tell format can now take eval, ask & tell as parameters, allowing to mix parts from different optimization strategies into new ones, ref #80 #81
fixed surrogate support for strategies with restart, ref #80
fixed initialization of prelambda in ACM surrogate strategy in order to work with high lambda, ref ref #57 #80
cleanup of generic strategy reuse scheme, ref #80 #81
