IJC gravity physics integration

thanks to Soo Kok for shairng his IJC gravity physics integration of simulations into lectures, tutorials and worksheets. download here https://dl.dropboxusercontent.com/u/44365627/eduLabJava2012-2013/Gravity/GravitationIJC2013.zip

added ability to fire to add velocity to a achieve eclipse orbit and select circular to achieve circular orbit by applying impulse in directions to get velocity at the correct speed and direction, perpendicular to radius. this feature helps in the learning of energies change as satellite move from one circular orbit to another circular as requested by soo kok.

better chance of increased student's learning when more time is used to use these simulations for practice of learning for the whole 3 weeks.

thanks
