constructor() {
    //set tokon
    Token.set('uuid','fasfasjfasjlk9312jkkfasjfaskl')
    Token.set('token','fasfasjfasjlk9312jkkfasjfaskl')
    //delete token
    Token.delete('uuid')
    Token.delete('token')
    //check if token exists
    Token.has('uuid')   //true or false
    Token.has('token')
  }
