- fix error: update temperature when replacing a block
- fix error in paramagnet heat capacity
- add Curie-Weiss magnet
- add Bfactor parameter for magnetic blocks
- examples: update for new "run" command interface
- in run command reduce the last step if needed to reach exact final time
- link type=field_heat_leak: dB2 parameter, heat leak proportional to (dB/dt)^2
