Grand is a simple random generator wrapper on math/rand seeded by entropy from crypto/rand

## Usage

Create a source that can be used by the randomizer. `NewSource` creates a source

with an optional seed. If there is no seed provided, a truly random seed will be 

derived from crypto/rand.

If a seed is provided, the function will not return an error. If entropy is used,

the function can return an error if it fails to read bytes from crypto/rand

```golang

// New source using entropy

src, err := grand.NewSource()

// New source from existing seed

src, _ := grand.NewSource(1552664635341843643)

```

The randomizer can use any math/rand source, not only ones created using this

package.

```golang

// New randomizer from source

rng := grand.New(src)

```
