Improve Point.setPosition

[tpietzsch]

Point.setPosition(Localizable) should use localize(long[]) instead of going dimension by dimension

imglib2/src/main/java/net/imglib2/Point.java

Lines 159 to 164 in 5b5de3a

	@Override
	public void setPosition( final Localizable localizable )
	{
	for ( int d = 0; d < n; d++ )
	position[ d ] = localizable.getLongPosition( d );
	}

Remember that Point and Localizable may have different numDimensions(). So think a bit about what is the right thing to do.
Also check RealPoint, probably something similar should be done there.
