Pet Park

Goal

The goal of this exercise is to develop a pet park smart contract. The specification of the contract is described in this readme and by the tests at tests/PetPark.spec.js. Once you implement the contract correctly, all the tests should pass.

We can have 5 kinds of animals in our pet park

Fish (AnimalType: 1)
Cat (AnimalType: 2)
Dog (AnimalType: 3)
Rabbit (AnimalType: 4)
Parrot (AnimalType: 5)

Complete this contract with following specifications for each function

add
- Takes Animal Type and Count. Gives shelter to animals in our park.
- Only contract owner (address deploying the contract) should have access to this functionality.
- Emit event Added with parameters Animal Type and Animal Count.
borrow
- Takes Age, Gender and Animal Type.
- Can borrow only one animal at a time. Use function giveBackAnimal to borrow another animal.
- Men can borrow only Dog and Fish.
- Women can borrow every kind, but women aged under 40 are not allowed to borrow a Cat.
- Throw an error if an address has called this function before using other values for Gender and Age.
- Emit event Borrowed with parameter Animal Type.
giveBackAnimal
- Throw an error if user hasn't borrowed before.
- Emit event Returned with parameter Animal Type.
