fortuna's Issues

Crashing

I wrote a simple problem, much in the same style as your example but when I call RadomData() I get this panic:

panic: runtime error: invalid memory address or nil pointer dereference
[signal 0xa code=0x2 addr=0x0 pc=0x52bc8]

goroutine 16 [running]:
runtime.panic(0x1eece0, 0x33b658)
/usr/local/go/src/pkg/runtime/panic.c:279 +0xc5

`seedFileName` example

Hey, thanks for the lib, looks great

The README says

The argument seedFileName is the name of a file where a small amount of randomness can be stored between runs of the program.

What exactly does this mean? Would it be possible to elaborate and give an example of what would make a good seedFile
