/**
 * SkeletalAnimation
 * This is the port of OGRE's Skeletal Animation Demo to Ogre4J
 * 
 * Config Sheet is an additional Ogre4J Feature.
 * You can switch to the config window using Alt+TAB
 * Due some problems with focus that I wasn't able to figure out till now
 * it is not recommended to switch back to OGRE Window with Mouse.
 * Till the problems are fixed, use for switching back again Alt+TAB
