Add some project tags

[spoeck]

Hi and Thanks for your cool lib!
I saw your lib 2 month (or longer) ago in my github stream and today I need it. So I started googling because I didn't remember the correct name of the lib. So I googled a lot of names but I found it after 30min in one Stackoverflow post. I had some suggestions for some tags I tried before:

• react comic arrows
• react whiteboard style arrows
• react self drawn arrows
• react cool arrows
• react arrows explain steps

I tried a lot but no result in google. Maybe this keywords help some others to find this awesome lib!

Hi @spoeck, thanks for your concern! I agree that the marketing needs a lot more work ;)
I'm currently occupied with another project but will look into making it more accessible soon. I'll leave this ticket open.
