Misleading TODO instruction on ERC721Mintable.sol

[albertsundjaja]

//  TODO's: Create CustomERC721Token contract that inherits from the ERC721Metadata contract. You can name this contract as you please
//  1) Pass in appropriate values for the inherited ERC721Metadata contract
//      - make the base token uri: https://s3-us-west-2.amazonaws.com/udacity-blockchain/capstone/
//  2) create a public mint() that does the following:
//      -can only be executed by the contract owner
//      -takes in a 'to' address, tokenId, and tokenURI as parameters
//      -returns a true boolean upon completion of the function
//      -calls the superclass mint and setTokenURI functions

On the last part of the file TODO's point number 2 -takes in a 'to' address, tokenId, and tokenURI as parameters

tokenURI should not be needed and could confuse students, tokenURI is already defined in the contract before ERC721Metadata
