PURPOSE

SLSHAREDISP_ATTACH Attachs to global display options

SYNOPSIS

function slsharedisp_attach(name, varargin)

DESCRIPTION

SLSHAREDISP_ATTACH Attachs to global display options

 $ Syntax $
   - slsharedisp_attach(name, ...)

 $ Arguments $
   - name:     the name of the invoker

 $ Description $
   - slsharedisp_attach(name, ...) attachs the current function to
     the global display. You can specify the following properties
       - 'show':       whether to show process information
                       (default = true)
       - 'indent':     the relative indent (default = 0)
     Please note that the actual properties set to the current displayer
     is determined by both the properties set here and the properties
     of the previous displayer in stack:
       new.show = current.show && previous.show;
       new.indent = current.indent + previous.indent;
