removed unnecesary files (now project is able to run)
Krzysiek P. changes - git forgives
Removed some unnecesary files
Together wit Krzysiek P. made 2nd step in collisions (wrote functions for normal vector, rotation, setting start rotation etc.)
Merge branch 'restore_branch' of github.com:przczuj/vpl-pg into restore_branch
Changes from Krzysiek P.: added angles to rotation matrix
Prepared template method for drawing rotated shapes
Added reaction to collisions
Corrected small bugs in BasicMath
created properties tab with editable properties
From Krzysiek P. Matrix-minor fix
From Krzysiek P. Fixed rotation and recalculating torques after change in acting forces
From Krzysiek P. Minor change in Force class in getForce(< changed to <=)
serialization should work; deserialization, I don't know - maybe it work; serialzation in applet not working - dont know why
Made conversion of angles between GUI and physics to make app more consistent
dam U netbeans... implemented XmlRigidBody.generateRigidBody()one again
fixes to serialization and deserialization; added momentum to rigid body property view + made velocity not editable (can be edited via momentum)
added mass to property view
Merge branch 'restore_branch' into 07_12_merge_branch
