e6d6f46b5d Proposal: Add new type of counter: FloatCounter (#5) 
* Add new type of counter: FloatCounter
* sometimes you need to count things with more precision than uint64
* FloatCounter also usefull if you need setable Gauge w/o callback func

* Fix PR review:
* sync.RWMutex -> sync.Mutex
* more idiomatic add/sub
