Summary of important user-visible changes for releases of the mechanics package

===============================================================================
mechanics-1.3.1   Release Date: 2013-xx-yy   Release Manager: Juan Pablo Carbajal
===============================================================================

* Functions with bug fixes
  rodmassmatrix: density function was assumed to be normalized. Now any density function should give the correct result for "s".

===============================================================================
mechanics-1.3.0   Release Date: 2012-24-08   Release Manager: Juan Pablo Carbajal
===============================================================================

* Functions with bug fixes
  masscenter

* Added functions
  rodmassmatrix

* Removed functions
  drawAxes3D is now a private function.

===============================================================================
mechanics-1.2.0   Release Date: 2011-10-16   Release Manager: Juan Pablo Carbajal
===============================================================================

* Rigid body object representation
@rigidbody
@rigidbody/display.m
@rigidbody/plot.m
@rigidbody/rigidbody.m
@rigidbody/subsref.m
 inertiamoment.m
 masscenter.m

* Functions that changed names
center_mass_poly2d.m --> masscenter.m
inertia_moment_ncpoly2d.m |
                          | - inertiamoment.m
inertia_moment_poly2d.m   |


* The functions second_moment_poly2d.m and area_poly2d.m can be found in the
geometry package. Mechanics is now dpeendt on that package.

* Minor fixes to other functions
* Major structure change of the package: multipackage
* Fixed the order of this NEWS file.

* verletstep : Verlet integrator.
* verletstep_boxed: idem with periodic boundary conditions.
* mdsim: Integrates a system of particle susing the algorithms above.
* several helper functions.
* Package ocframe integrated.
