* The following four functions set the prices and amounts.

* invoking any of them will cause other splits in the transaction
* to be modified so that the net value of the transaction is zero.
*
* The xaccSetShareAmount() method sets the number of shares
* that the split should have.
*
* The xaccSetSharePrice() method sets the price of the split.
*
* The xaccSetValue() method adjusts the number of shares in
* the split so that the number of shares times the share price
* equals the value passed in.
*
* The xaccSetSharePriceAndAmount() method will simultaneously
* update the share price and the number of shares. This
* is a utility routine that is equivalent to a xaccSplitSetSharePrice()
* followed by and xaccSplitSetAmount(), except that it incurs the
* processing overhead of balancing only once, instead of twise.
