Very first graphics. Moving, rotation, adding cubes, simple editing etc.
Test commit
Merge branch 'master' of github.com:przczuj/vpl-pg
Merge branch 'gui_rewind'
removed unnecesary files (now project is able to run)
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
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 <=)
Made conversion of angles between GUI and physics to make app more consistent
Merge branch 'restore_branch' into 07_12_merge_branch
