 +=====  FT_PLOT_CROSSHAIR =====
 +Note that this reference documentation is identical to the help that is displayed in MATLAB when you type "help ft_plot_crosshair"​.
 +  <a href=/​reference/​ft_plot_crosshair><​font color=green>​FT_PLOT_CROSSHAIR</​font></​a>​ plots a crosshair at a specified position in two [x, y] or three
 +  [x, y, z] dimensions. ​
 +  Use as
 +    h = ft_plot_crosshair(pos,​ ...)
 +  where pos is the desired position of the crosshair. The handles of the lines are
 +  returned.
 +  Optional input arguments should be specified in key-value pairs and can include
 +    '​color' ​   = [r g b] value or string, see PLOT
 +    '​parent' ​  = handle of the parent axes
 +    '​handle' ​  = handle of the existing line objects to be updated
 +  ​
 +  You can specify the handles of existing line objects which will be then updated,
 +  rather than creating a new set of lines. If both parent and handle ar specified,
 +  the handle option prevail.
 +  ​
 +  Example
 +    ft_plot_crosshair([0.5 0.5], '​color',​ '​r'​)
