Implement summarize events for multiple subjects

Can you remind me again what the functionality is? Basically just a DF with unique events and count and such? (what would be useful here?)

I think I simply got cofused in the Readme.md as it is still included there :-D

I think I envisioned some kind of text-summary of events (e.g. frequency, which events how many times) - potentially also a matrix, which event is followed by which event (and how much overlap? dunno how to do that). Also maybe a range of each variable (or a in-line histogram) ~~ cue some procrastiation music ~~ oookay, and here I have a prototype for this

    using UnicodePlots
    using Term
    using Printf
    using Statistics

h(name,d) = 
TextBox(@sprintf("{bold}%s{/bold} \nμ=%.2f,σ=%.2f\nmin=%.2f\nmax=%.2f",name,mean(d),std(d),minimum(d),maximum(d)),fit=true,) * 
(histogram(d,vertical=true,height=1,grid=false,stats=false,labels=false,border=:none,padding=1,margin=0)|>UnicodePlots.panel)
h("testFactor",d)|>print

should be easily stackable for multi-event purposes :)

Edit: Number of events would be nice as a number too

EditEdit: This requires UnicodePlots.jl as a requirement

Update on this + ToDos:

• [x] function to translate all (i.e. from all subjects) events into a tidy data frame (for AoG plotting)
• [ ] quick summary function as described above
