/**
 * @dev Transfers collateral from the source account number to the destination account
 *      number. Emits a `BorrowPositionOpen` event before the Operation executes.
 *      This enables the offchain data indexers to see the position being opened and
 *      start watching for Actions.

 * @param _fromAccountNumber    The index from which `msg.sender` will be sourcing the
 *                              deposit
 * @param _toAccountNumber      The index into which `msg.sender` will be depositing
 * @param _collateralMarketId   The ID of the market being deposited
 * @param _amountWei            The amount, in Wei, to deposit
 * @param _balanceCheckFlag     Flag used to check if `_fromAccountNumber`, 
 *                              `_toAccountNumber`, or both accounts can go negative 
 *                              after the transfer settles. Setting the flag to

 *                              results in neither account being checked.
