Second Major Changes

Hi Shu Yang, 

~~My computer ram got angry with me.~~

Still work in progress for tidying up plus step 3, but you should be able to see the changes now. The repo directories are cleaned up as well.

(Not sure if you'll notice the differences, but proportions and sizes have changed. Step 3 is a bit fuzzy now so just ignore it first)

I'll commit more code and tidy things up a bit more in the next few commits :)
The readme is updated with more To Dos for the next few commits as well.

Regards,
Chris
