/* This is a scaled down version of the routine that would be needed
* to fully convert a gnc-commodity to a scheme data structure. In an
* attempt to optimize the speed of price quote retrieval, this
* routine only converts the fields that price-quotes.scm uses. Since
* it converts these fields all at once, it should prevent multiple
* transitions back and forth from Scheme to C to extract
* the data from a pointers to a gnc-commodity (the older method).
* This is *not* a reversible conversion as it drops data.
*
* When this routine was written, gnucash retrieved all quotes into
* the user's default currency. (Did earlier version do any
* different?) This routine inserts that default currency into the
* returned structure as another optimization.
