Remove AlignFrame.main() method and refactor related static methods

jalview.gui.AlignFrame appears to have some code that really shouldn't be there:


  public static int[] getStartEnd(int[] aligmentStartEnd,
          List<int[]> hiddenCols)
  {
    int startPos = aligmentStartEnd[0];
    int endPos = aligmentStartEnd[1];

    int[] lowestRange = new int[] { -1, -1 };
    int[] higestRange = new int[] { -1, -1 };

    for (int[] hiddenCol : hiddenCols)
    {
      lowestRange = (hiddenCol[0] <= startPos) ? hiddenCol : lowestRange;
      higestRange = (hiddenCol[1] >= endPos) ? hiddenCol : higestRange;
    }

    if (lowestRange[0] == -1 && lowestRange[1] == -1)
    {
      startPos = aligmentStartEnd[0];
    }
    else
    {
      startPos = lowestRange[1] + 1;
    }

    if (higestRange[0] == -1 && higestRange[1] == -1)
    {
      endPos = aligmentStartEnd[1];
    }
    else
    {
      endPos = higestRange[0] - 1;
    }

    // System.out.println("Export range : " + startPos + " - " + endPos);
    return new int[] { startPos, endPos };
  }

  public static void main(String[] args)
  {
    ArrayList<int[]> hiddenCols = new ArrayList<int[]>();
    hiddenCols.add(new int[] { 0, 0 });
    hiddenCols.add(new int[] { 6, 9 });
    hiddenCols.add(new int[] { 11, 12 });
    hiddenCols.add(new int[] { 33, 33 });
    hiddenCols.add(new int[] { 50, 50 });

    int[] x = getStartEnd(new int[] { 0, 50 }, hiddenCols);
    // System.out.println("Export range : " + x[0] + " - " + x[1]);
  }
