Contract module that allows children to implement role-based access\n control mechanisms. This is a lightweight version that doesn't allow enumerating role\n members except through off-chain means by accessing the contract event logs. Some\n applications may benefit from on-chain enumerability, for those cases see\n {AccessControlEnumerable}.\n Roles are referred to by their `bytes32` identifier. These should be exposed\n in the external API and be unique. The best way to achieve this is by\n using `public constant` hash digests:\n ```\n bytes32 public constant MY_ROLE = keccak256(\"MY_ROLE\");\n ```\n Roles can be used to represent a set of permissions. To restrict access to a\n function call, use {hasRole}:\n ```\n function foo() public {\n require(hasRole(MY_ROLE, msg.sender));\n ...\n }\n ```\n Roles can be granted and revoked dynamically via the {grantRole} and\n {revokeRole} functions. Each role has an associated admin role, and only\n accounts that have a role's admin role can call {grantRole} and {revokeRole}.\n By default, the admin role for all roles is `DEFAULT_ADMIN_ROLE`, which means\n that only accounts with this role will be able to grant or revoke other\n roles. More complex role relationships can be created by using\n {_setRoleAdmin}.\n WARNING: The `DEFAULT_ADMIN_ROLE` is also its own admin: it has permission to\n grant and revoke this role.

This is a lightweight version that doesn't allow enumerating role members except through off-chain means by accessing the contract event logs. Some applications may benefit from on-chain enumerability, for those cases see {AccessControlEnumerable}. Roles are referred to by their `bytes32` identifier. These should be exposed in the external API and be unique. The best way to achieve this is by using `public constant` hash digests: ``` bytes32 public constant MY_ROLE = keccak256(\"MY_ROLE\"); ``` Roles can be used to represent a set of permissions. To restrict access to a function call, use {hasRole}: ``` function foo() public { require(hasRole(MY_ROLE, msg.sender)); ... } ``` 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 roles. More complex role relationships can be created by using {_setRoleAdmin}. WARNING: The `DEFAULT_ADMIN_ROLE` is also its own admin: it has permission to grant and revoke this role.
