Human friendly random name generator for tests

Human-friendly Random Name Generator

This little library generates human friendly random identifiers. For example, given the following code,

RandomNameGenerator rnd = new RandomNameGenerator(0);

for (int i=0; i<10; i++)
    System.out.println(rnd.next());

The output will be as follows:

constructive_carrot
flexible_designer
linear_fund
popular_leaf
steady_parent
abstract_rest
controversial_supply
fragrant_absorption
lively_cassette
powerful_destruction

In testing, these names are more useful than number-based random names, as they are more memorable to humans.

The generator is based on a fixed dictionary of about 600 adjectives and 2400 nouns, thereby producing little more than 1.5 million unique combinations. If you keep calling the next() method beyond this limit, it'll start producing the same name again.

The generator is pseudo-random, meaning if you provide the same seed value, it'll always generate the same sequence of identifiers.
