Look for Morning/Evening Star Patterns in a OHLC price series

1	CSPStar(TS, n=20, minbodysizeMedian=1, maxbodysizeMedian=1)

`TS`	xts Time Series containing OHLC prices
`n`	number of preceding candles to calculate median candle length
`minbodysizeMedian`	minimum candle length in relation to the median candle length of the formation's first candle
`maxbodysizeMedian`	maximum candle length in relation to the median candle length of the formation's second candle

Number of candle lines: 3

Morning Star:
The market is in downtrend. The first candlestick is a long black body; the second one is a small real body of either color. It is characteristically marked with a gap in lower direction thus forming a star. Finally we see the black candlestick with a closing price well within first session's black real body. This pattern clearly shows that the market now turned bullish.

Evening Star:
The market is in uptrend. The first candlestick is a long white body; the second one is a small real body of either color. It is characteristically marked with a gap in higher direction thus forming a star. Finally we see the black candlestick with a closing price well within first session's white real body. This pattern clearly shows that the market now turned bearish.

A xts object containing the columns:

`MorningStar`	TRUE if Morning Star pattern detected
`EveningStar`	TRUE if Evening Star pattern detected

The function filters patterns that look like morning/evening stars, without considering the current trend direction. If only pattern in uptrends should be filtered, a external trend detection function must be used. See examples.
