    Bancor Converter v0.6

    The Bancor version of the token converter, allows conversion between a smart token and other ERC20 tokens and between different ERC20 tokens and themselves.

    ERC20 connector balance can be virtual, meaning that the calculations are based on the virtual balance instead of relying on
    the actual connector balance. This is a security mechanism that prevents the need to keep a very large (and valuable) balance in a single contract.

    The converter is upgradable (just like any SmartTokenController).

    WARNING: It is NOT RECOMMENDED to use the converter with Smart Tokens that have less than 8 decimal digits
             or with very small numbers because of precision loss


    Open issues:
    - Front-running attacks are currently mitigated by the following mechanisms:
        - minimum return argument for each conversion provides a way to define a minimum/maximum price for the transaction
        - gas price limit prevents users from having control over the order of execution
      Other potential solutions might include a commit/reveal based schemes
    - Possibly add getters for the connector fields so that the client won't need to rely on the order in the struct
