changed spring mesh optimizer,  it now does a more accurate physical
simulation with adjusting discrete step sizes according to the maximal
force and speed of any vertex

TODO more bugs expected, fix accuracy problems in spring mesh and vertex
by using double, improve performance by not iterating sets and
maps where an array would do
made SpringMesh use double instead of float for calculations
do not print the percentage in smoothness filter
use arraylist where arraylists are returned
almost full float to double transfer of vertex and spring mesh
Transform_SpringMesh for testing the adjusted optimizer
Merge branch 'master' into spring-mesh2
TransformMesh constructor with PointFactory/PointMatchFactory

TODO not yet tested, needs to be extended to SpringMesh
Merge branch 'spring-mesh2' into spring-mesh3
cosmetics for alternative jars
comments fixed
Merge branch 'master' into spring-mesh2
Merge branch 'spring-mesh2' into spring-mesh3
Merge branch 'master' into spring-mesh3
