Problem Statement: Speed Out Evil Aliens

This is the EASY 250 points competition that the Evil Aliens have given to the people of Earth. Learn More and Register for this competition before submitting a solution to this problem.

The acceleration tool of the spaceship is broken and they can now only set the speed manually to accelerate in the designated way. They have given us a dumb website to help them with that. They asked us to create a simple speed acceleration calculator for them to help them know the speed they need to keep their power booster engines on to help their spaceship travel out of Earth.

What do you need to do?

• You have to grab this starter pack: https://github.com/kriasoft/react-starter-kit
• Add a new tab at the left side of `About` tab in the header name it as `Speed Counter` https://take.ms/Q6IIj , so once clicked on this `Speed Counter` tab, the simple Speed Counter feature will be revealed on the website and let the Evil Aliens will know the speed they need to keep when they want to accelerate in a systematic fashion.
• The page should have three elements: `Current Speed 0` is used to identify the current speed value, `Increase Speed` button will increase the speed by 1 * 10%, `Decrease Speed` button will decrease the speed number by 1 * 10%
• Important things to Note: The speed counter starts from 0, The speed counter never gets below 0, The speed counter never exceeds 2, which means when the counter reaches 2, it will stay at 2 for further `Increase Speed` operation.
