a KMyMoneyMoney object was assignment, construction and destruction.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">By using implicit sharing combined with a shared zero value, copying
on assignment and construction can be greatly reduced.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Implicit sharing was easy to implement using QSharedDataPointer.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Bumped the library version because API changes were necessary. The
mpq_class &valueRef() const method was bad beacause it was returning
a non-const reference from a const function. Now There is a const
version which will not detach the shared data while the non-const
version will detach from the shared data.</p>

Note that the second run also contains some MyMoneyMoney optimizations based on this feature (subject of a different review request).</p></pre>
