Pebble manager

Pebble manager is responsible for direct blockchain interaction with the Pebble (PBL) contract.

The source of contract that was used during development is located in:
contracts/Pebble.sol - This contract is exactly the same as the live one, except for two things - check the notes below
build/contracts/Pebbles.json - Compiled JSON version of the contract

Notes: Development contract expects founder address in the constructor, however live contract have it defined already. Also there's an additional method for development purpose which is receivePbls.

---

getInstance()

Method that will return the existing or assign a new instance of Pebble contract. Pebble contract address should be defined in the js/config/index.js file.

Note: It would NOT deploy the contract itself, it will connect to existing already deployed instance.

---

createInstance()

Method will create and **deploy new **instance of Pebble contract to the blockchain network

---

approve(spender, player, value)

Method will approve specified amount of PBL that can be used by the user

spender - Address of a user who will be allowed to get PBLs

payer - Address of a user from who PBLs will be withdrawn

value - Amount of PBLs that should be transferred

---

balanceOf(address, callback)

Method will return the balance of PBLs for the specified address

address - wallet address of the user to get balance of

callback - expects the callback function that will be triggered after the balance is received

---

receivePbls(receiver)

This is a DEVELOPMENT method that will give PBLs to a user.

receiver - wallet address of the user who PBLs should be transferred to

Note: Keep in mind that this method will only work with the pebble contract that is in the repository and not the live contract, because there's a specific method in the development contract that does not exist in the live one.
