Added first parts/design of 2D Solver
Uncommented and modified some convenient funktions for Vec4
Added a prototype of a not yet really working 2Dplugin
Made modifications in order to test the code
Added lots of debug output and debugged some constants
Changed some initial values so that the computation works better...
Debugged Timederivates, made timesteps a lot smaller so sampling is much more precise and played a bit with the parameter
Debugged 2D forces and modified parameter a bit
Changed parameter of some Initialvalues
Debgged initail value
Added simple euler integration for 2D solving step
Merge remote-tracking branch 'origin/feature/gran_sim_prj' into feature/gran_sim_prj
Restructured Code a bit
Changed minor stuff
Added a hashlistcreator in order to detect collisionpartner for 2D and made some minor unnecessary changes in particle processing
Changed minor stuff in order to check Hashmap creation
Added faster collisionDetectionStructure (see Teschner03). Further changed some values in Order to do some measurements and removed some print statements...
Refactored the Code a bit
