0029 //  Generator with multiple modes: uniform, free, axis, fixed)
0030 //
0031 //  Primary generator that can be configured using modes to either:
0032 //    - 'uniform' direction secondaries       (default)
0033 //    - 'free'    which is configured by UI - initialised in con/tor
0034 //    - 'axis'    directing secondaries by rotation to x, y & z axis
0035 //    - 'fixed'   along x axis, and near it ( y = 0.1 or z = 0.1)
0036 //
