Basic Shape classes and test for them
* Created basic MrObject and MrShape classes.
* Created MrShape daughter classes: MrBox and MrSphere.
* Created shape_test application - collection of tests for MrShape class (and his daughters)
  Run test simply:

    >./shape_test

  Now there are two tests:
 1) Unitarity test - checks if transformation matrix for shape, and inverse-transformation matrix produce UNIT matrix.
 2) MC test (MrBunny-test) - calculate a volume of Bunny using MC method.
    Bunny is composed of primitives(MrBox and MrSphere), and each primitive can test,if a given point is inside its volume.
    This test produces file "shp.txt" with probing points coordinates.

* Created root script to draw bunny:

     >root -l scrits/plot_shp.C

You should see points inside MrBunny in blue, outside - in black
