Migration and testing

In this version main direction of work was concentrated on creating migrations and testing smart contracts, which resulted in finding some bugs (and fixing them).

Now we can more freely change smart contracts and be sure that if something goes wrong we'll know it before it's too late :)

Basic math wrapper

This version's pool is just basic math wrapper which may be used to call calculation functions (but you probably shouldn't use it)

Contracts currently will not work properly even if they compile.
