/**
  Must be called with a string containing a unique identifier for the
  commodity.  If an commodity with a matching exchange_code is
  found, the function immediately returns with a pointer to that
  commodity.  Otherwise, the user may be prompted to select a GnuCash
  account or create a new one (in both cases, the exchange_code is written
  written to the commodity's exchange_code field, overwriting anything that
  was there before.

    @param exchange_code The string containing the code for which you
    want a matching commodity.  A CUISP code or similar UNIQUE code.
    The stock ticker is NOT appropriate, unless you have no other option.

    @param auto_create If 0, if the exchange_code value in unknown,
    the function returns NULL, otherwise, the user will be asked to 
    create a new account.

    @param default_fullname A human-readable description of the commodity, such
    as the stock name.  Can be NULL. If it is not NULL, it will be shown
    to the user when selecting a commodity.  It will also be used as
    the default if a new commodity is created.

     @param default_mnemonic  Usually the stock ticker or similar. Can be NULL.
     If it is not NULL, it will be shown
    to the user when selecting a commodity.  It will also be used as
    the default if a new commodity is created.

  @return A pointer to the found or created commodity, or NULL if no
  account was found or created.
