Generate Unique ID.

```

go get github.com/newm4n/go-jenius-unique

```

## HOW ???

You should read the test class  `idgen_test.go` on how to use the library.

TL;DR :

```

import (

	"jeniusunique"

)

...

unique24CharString := jeniusunique.GetUniqueGenInstance().NewXReferenceNo(24)

...

```

`NewXReferenceNo` accept an number parameter which is the length of string to be generated.

## HOW YOU DO IT ?

```

nn = last known nano second time stamp in int64

i = mac-address in int64

func GetUniqueGenInstance(l) string

    n = nano second timestamp in int64

    c = 0

    if n == nn {

        c++

        unique = n xor i xor c

    } else {

        c = 0

        unique = n xor i xor 0

    }

    nn = n

    if len(unique) < l {

        append unique with random char until it has len == l

    }

}

```
