Dear,

I'm trying use the Proton CEP, how is showed into Proton user guide,
although, not run fine when my  logical rules are related at the function
"distance(x1,y1,x2,y2)"
on a expression AuthoringTool, the documentations aren't clear for me, how
could use this function? The demos projects, don't show how can I use it,
could you show a example? I'm new in the proton API. Thank you!

Best regards,
Herbert Diniz
