 * @dev Contract module that allows children to implement role-based access

 *
 * Roles are referred to by their `bytes32` identifier. These should be exposed

 * ```
 * bytes32 public constant MY_ROLE = keccak256("MY_ROLE");

 * Roles can be granted and revoked dynamically via the {grantRole} and
 * {revokeRole} functions. Each role has an associated admin role, and only
 * accounts that have a role's admin role can call {grantRole} and {revokeRole}.
 *
 * By default, the admin role for all roles is `DEFAULT_ADMIN_ROLE`, which means
 * that only accounts with this role will be able to grant or revoke other

/*
    ###### Purpose of contract ########
    This smart contract allows users to securely stake various tokens 
    representing their share in Invictus funds (c10 etc).

    Staking tokens for certain periods of time will entitle users
    to rewards (ICT tokens).

    ICT tokens to be bought off the open-market by Invictus with fund fees,
    to create value for token holders.
