fix orbit traces
Merge branch 'dev' into speedup
display impulse deviation in cli client
Merge branch 'oldvec2d' into dev
add simple arg parser

(add random fiddeling from a previous branch *selfslap*)
Merge branch 'dev' into args
gen_client implements some simple fps counter

screws a bit with the orbit tracking of graphic.py though
Merge branch 'commonclient' into dev

Conflicts:
	bin/graphic.py
simplify linear_combination for perpedicular a & b
Merge branch 'args' into dev
add script for performance testing
first rework of engine with numpy
finish first numpy version, adapt graphic, rest to follow
add "benchmarking" and some python-foo in the View

    gravsim.view.View.__init__ now automatically inserts the namespace
    of the processed argparser into the namespace of the View to avoid
    boilerplate
port all bin/* to the new gravsim.view.View class

    gravsim.view.View now also takes care of timing stuff
add function to get impulse of the system

    somethings weird with it though
Merge branch 'numvec' into dev
Merge branch 'dev'
