move semantic

we should make sure that data structures that we expect to be big have proper support for the move semantic.

It is a new fancy thing in C++11 that allow you to bypass copies when they are unnecessary. For instance, if you do "SomeThingBig a = somefunctionwhichreturnbycopy();" then the compiler can tell that the anonymous object returned won't be used anymore and a can be built by "stealing" the data from the anonymous object rather than copy them. It can make the API a lot simpler because we won't feel like we have to pass things by pointer or by reference for the only sake to avoid a copy. I have never implemented that myself, so I need to make sure how that works.
