//|          the 'LSTM       AI' indicator.                          |
//| Is derived from the CExpertSignalAIBase class.                   |
//| Only the network topology differs from the other AI signals: an  |
//| input layer feeds a single LSTM layer before the common tapering  |
//| hidden-layer stack (see AddCustomLayers).                         |
