--Sorting function: Alpha

--Draw line on monitor
function draw_line(x, y, length, color, monitor)

--Draw line in Terminal
function draw_line_term(x, y, length, color)
    term.setBackgroundColor(color)

-- Compact Monitor Write function

-- Compact Terminal Write function
function CTWrite(col, row, text, color)
    color = color or colors.white
    term.setCursorPos(col,row)

    term.write(text)
end

-- Get number of items in a table
function tablelength(T)
  local count = 0
  for _ in pairs(T) do count = count + 1 end
  return count
