*According to litarature a Black spinning top candle is made of Black body, i.e closing
*price is lower than the opening price.There must be one shadow present. One of the shadows must
*be longer than the body. The candle can appear as a long or short candle.
* The goal of this class is to calculate if a candle
*is Black spinning top candle or not.
