added SetEnv_rub_mn2standalone.csh to use extracted minuit2 standalone library from root 6.33, the environment variable MINUIT2_STANDALONE is now used in Jamroot_rub_AL9_mn2standalone to link to this minuit2 lib to pawian

minor modifications for calculating the 4-vectors of mother mother reference system in the decay levels >=3

bugfix in PwaUtils/FVectorIntensityDynamics, fixed false phsp factor calculation; added keep_alive to acceptor in NetworkServer; minor changes in SetEnv_rub_mn2standalone.bash script

SetEnv_rub_mn2standalone.bash: added option to set a new pawian env (removing/overwriting existing env) and removed usage of already sourced root (need to source same root version from compilation to avoid crashed, so now will allways source root specified in user var ROOT_DIR)

Added Jamroot_rub_AL9_mn2standalone to support new minuit2 extracted from root as standalone package, since there are no other external packages the env variable is renamed from extern to MINUIT2_STANDALONE (the subdirs in minuit2 have changed compared to old version, now need to include <Minuit2Path>/include/Minuit2 instead of just <Minuit2Path>/include in Jamfile); Added a new bash script SetEnv_rub_mn2standalone.bash to setup pawian with new minuit2 version, its not needed to run the script inside the pawian directory and it will also check if another pawian is already loaded (checks if TOP_DIR exists), if root is already sourced this step will be skipped (else load root defined in script) and appends/prepends the LD_LIBARAY_PATH and PATH safe; MODIFIED NETWORK CLIENT AND SERVERgit add SetEnv_rub_mn2standalone.bash -! Modified the network client and server to keep the connections and not permanently close and reconnect, this should prevent that there are thousands of tcp connections blocking ports in TIME_WAIT status. With the open connections there was an issue with the heartbeat, that was sendet from a second client stream to the server, so the heartbeat is completely removed for now (all changes are marked with comments in the code)

added option to minimize w/ Adam algorithm; added setenv-script for using MINUIT2 standalone version from ROOT

added minimization with numerical gradient calculation; changed WignerD calculation for multipole amplitudes

changed _decProjectionIndex to _projectionCompareIndex of evalPhaseCompare method in FVectorCompareDynamics.cc and added determination of _projectionCompareIndex to FVectorComapreDynamics constructor

now *.cc except *App.cc files will be added via wildcard to libs and added directory build to .gitignore

added CMake to build pawian, for now required packages need cmake support so find_packages will find them

added mathematica script for the P-vector calculation for COMPASS data of the pi1(1600) parametrization
