    * Must have:
    * - three white candlesticks with consecutively higher closes
    * - Greg Morris wants them to be long, Steve Nison doesn't; anyway they should not be short
    * - each candle opens within or near the previous white real body 
    * - each candle must have no or very short upper shadow
    * - to differentiate this pattern from advance block, each candle must not be far shorter than the prior candle
    * The meanings of "not short", "very short shadow", "far" and "near" are specified with TA_SetCandleSettings;
    * here the 3 candles must be not short, if you want them to be long use TA_SetCandleSettings on BodyShort;
    * outInteger is positive (1 to 100): advancing 3 white soldiers is always bullish;
    * the user should consider that 3 white soldiers is significant when it appears in downtrend, while this function 
    * does not consider it
