Functions:

void geBox_Set(geBox* Box, float xScale, float yScale, float zScale, const geXForm3d* Transform);

Call this to set up a Box for the first time or when the Box's local frame axes scale(s) change

void geBox_SetXForm(geBox* Box, const geXForm3d* Transform);

Call this to set the Box's transformation matrix (does not change the scales of the Box's local frame axes)

geBoolean geBox_DetectCollisionBetween(const geBox* Box1, const geBox* Box2);

returns GE_TRUE if the boxes overlap, GE_FALSE otherwise
