Stipple.jl can't get notify working

New to Julia

All hail @hhaensel for taking the time to help a noob. This is HIS code not mine, you know this because IT WORKS, it’s got a much better approach and there is lashings of things for noobs to unpack. Just take a look at the random generator, or the manner in which the dataframe is updated. Clearly a man who knows where his towel is.

The fact that, ONCE AGAIN, my inability to read is front and center. I found this code from @hhaensel to be an excellent learning tool.
