  // functionality is as follows:
  //
  // Libraries utilized: SafeMath
  // (https://github.com/OpenZeppelin/zeppelin-solidity/blob/master/contracts/math/SafeMath.sol)
  //
  // - CardBase: This contract stores the fundamental instruments necessary to
  // run ProjectEther. Included are storage elements and basic functionality of
  // cards.
  //
  // - CardBattle:
  //
  // - CardForge: This contract contains all the advanced functionality and
  // permission related elements. Included are features for card packs, sale of
  // card packs, and admin perms.
  //
  // - CardMarketplace:
  //
  // - CardMaster: This file manages all the creator and admin permissions and
  // constraints for child contract functions.
  //
  // - CardOwnership: This provides the methods required for basic non-fungible
  // token transactions, following the draft ERC-721 spec.
