To set bundled outputs:
rs.setBundledOutput("left", colors.red + colors.blue )
rs.setBundledOutput("left", rs.getBundledOutput() + colors.yellow )
rs.setBundledOutput("left", rs.getBundledOutput() - colors.red )
rs.setBundledOutput("left", 1337 )

To read bundled inputs:
red = rs.testBundledInput( "right", colors.red )
both = rs.testBundledInput( "right", colors.red + colors.blue ) 
number = rs.getBundledOutput( "right" )
