*  @brief
*    Scene node move input controller modifier class
*
*  @remarks
*    When using the unchanged virtual standard controller:
*    Use a/w/d/s or cursor keys to walk. 'PageUp/PageDown' to move upwards/downwards.
*    Hold the 'shift'-key to speed up, hold the 'strg'-key to slow down.
*
*  @note
*    - Primary intended for rapid prototyping
