Minimal Token

It is now time to create our first token. We will start with a minmal implementation of a token.

Instructions

• Create a Smart Contract MinimalToken

• Create a constructor function that takes a positive number as parameter and give an initial balance of tokens to the contract deployer.

• Create a public function balanceOf(address) to retrieve the balance of each user given an address

Hint: You can declare a variable public to have an implicit public getter function of the same name.

• Create a function transfer(address,uint) that takes as parameters an address and a positive integer and, providing the sender has sufficient funds, moves the token to the provided address.
