Functions to Override

The following functions have been implemented on this contract & are available to be overridden to add custom logic:

* @notice Lets an authorized address mint tokens to a recipient.
* @dev The logic in the `_canMint` function determines whether the caller is authorized to mint tokens.
* @param _to The recipient of the tokens to mint.
* @param _amount Quantity of tokens to mint.
function mintTo(address _to, uint256 _amount) public virtual {
require(_canMint(), "Not authorized to mint.");
require(_amount != 0, "Minting zero tokens.");

_mint(_to, _amount);
* @notice Lets an owner a given amount of their tokens.
* @dev Caller should own the `_amount` of tokens.
* @param _amount The number of tokens to burn.
function burn(uint256 _amount) external virtual {
require(balanceOf(msg.sender) >= _amount, "not enough balance");
_burn(msg.sender, _amount);
