Create entry point level documentation

[punkto]

topics:

1. Line follower competition rules (https://github.com/open-robosports/normativa-velocistas )
2. Generic line follower structure (differential motion, line sensing)
3. RustyBugA hardware (Available peripherals, MCU, MCU-peripherals connection)
4. RustyBugA firmware (General processes the line follower should do (line sensing, motors control, PID))

Language: English

let's divide this in tasks:

• [x] Line follower competition rules (https://github.com/open-robosports/normativa-velocistas )
• [x] Generic line follower structure (differential motion, line sensing)
• [x] RustyBugA hardware (Available peripherals, MCU, MCU-peripherals connection)
• [x] RustyBugA firmware (General processes the line follower should do (line sensing, motors control, PID))

I'm taking the "Line follower competition rules" part. Making also the docs structure

I'm going to make the file structure of the docs in a branch.

I`ll take the "RustyBugA hardware (Available peripherals, MCU, MCU-peripherals connection)" part.

I'll take RustyBugA firmware

I think we have enough to start with :D. @eLeDe @hmightypirate if you have the time, please give it a look.
