NotEnoughValuesToPickException when only one value is passed about fluent-random-picker

[SapiensAnatis]

That's fair enough. I eventually came up with what I consider to be an acceptable workaround - I created my own implementation of IPick which takes in a single value and always returns that value. Then I just used a factory method to return either that in the 1-element case, or a normal picker in every other case.

Hello, it was implemented like this for 2/3 reasons:

1. consistency: The fluent syntax does not allow something like Out.Of().Value(3).Pick(). It compiles only when calling AndValue() at least once.
2. • In your case, it is an unexpected behavior, but in other cases, it could be useful, because maybe, someone has accidentally passed only 1 value.
   • Especially when additionally specifying weights (e.g. "please pick form the following values: letter z with weight 37; that's it"), from the library point of view, it looks more like it received wrong input.

To be honest: I don't know what the best solution is (status you, your suggestion, allowing to configure the behavior) and I can't promise you to change the logic.
