Misleading documentation for LocationIndexedLine

[FObermaier]

A user of NetTopologySuite reported that there is some misleading documentation for LocationIndexedLine.project and LocationIndexedLine.indexOf. Both state to do only almost similar things while they exactly the same thing:

jts/modules/core/src/main/java/org/locationtech/jts/linearref/LengthIndexedLine.java

Lines 116 to 136 in 1c0902d

	/**
	* Computes the minimum index for a point on the line.
	* If the line is not simple (i.e. loops back on itself)
	* a single point may have more than one possible index.
	* In this case, the smallest index is returned.
	*
	* The supplied point does not <i>necessarily</i> have to lie precisely
	* on the line, but if it is far from the line the accuracy and
	* performance of this function is not guaranteed.
	* Use {@link #project} to compute a guaranteed result for points
	* which may be far from the line.
	*
	* @param pt a point on the line
	* @return the minimum index of the point
	*
	* @see #project(Coordinate)

	public double indexOf(Coordinate pt)
	{
	return LengthIndexOfPoint.indexOf(linearGeom, pt);
	}

	/**

	* If more than one point has the closest distance the first one along the line
