Algorithm:

1. NodeID = ((HostID << PIDLengthInBits) | PID) << counterLengthInBits

2. Timestamp = Now() - ToTimestamp(20.02.2016, 14:23:57)

3. UniqueID = Timestamp | NodeID | Counter

Counter - increment atomic counter less than predefined defaultSequenceBits const

Luigi provides 3 basic methods for IDs generate:

• Generate() - single value
• GenerateSlice(n) - slice of UIDs with n values
• FillChannelFillChannel(ch chan<- *big.Int) chan error - continuously fill ch channel with UIDs

Luigi can generate UIDs of 3 types: uint64(supports millisecond timestamp), string and BigInt(supports nanosecond timestamp)
