fix #273

[dimus]

Can you add to documentation how to use UUID generator?

[alexander-myltsev]

Here is documentation on that part. What do you think is the best place to put it in README?

UuidGenerator

gnparser is also provided with facilities to create UUID version 5 out of scientific name string. It uses globalnames.org domain for DNS namespace. There is a 1:1 relationship between the string and the corresponding UUID, so it allows globally connect data about a name string originated from independent sources without a need to negotiate identifiers. You can find more information about UUID v5 from the original RFC4122 document.

Code sample to use it is as follows:

scala> val gen = org.globalnames.UuidGenerator()
scala> gen.generate("Salinator solida")
res0: java.util.UUID = da1a79e5-c16f-5ff7-a925-14c5c7ecdec5

I added the example code to Scala example in README
