improved set of setters/getters in public objects
added setter / getter for fplot and activating output to file from the library
updated first changelog, as for v0.7, in order to start with milestones and public version
fixed get_algo function name
added comment on EDM with geno/pheno transform
added support for pheno transform gradient and edm with transform, ref #45
added support for pheno transform gradient and edm with transform, ref #46
Merge branch 'master' of github.com:beniz/libcmaes
added support for gradient injection along with geno/pheno transform, ref #47
fixed first iteration of gradient injection, ref #47
added support for numerical gradient injection + option in test_functions
Merge branch 'master' into minos

added support for numerical gradient injection to bbob'2013 benchmark
numerical gradient now increases overall optimization budget
simplifed update of nevals
lowered the numerical gradient overall budget to dim + 1
fixed progress function: now using up-to-date consumed budget evaluation
made expected distance to minimum (edm) computation optional when optimization has completed as the numerical gradient consumes the objective function evaluation budget
Merge branch 'master' into minos
added control of threading of objective function evaluations, closes #42
