Dino catalog

fixed houndci comments. please review this
I don't see where DinosaurParser is being used, but it may be easier to have an initialize which calls parse so it happens automatically (as I assume that class' solo purpose)

```
class DinosaurParser
  def initialize
    @result_dinosaurs = []
    parse_dinodex
    parse_african_dinosaurs
  end

  def parse_dinodex
    CSV.foreach("filename", headers: true) do |row|
    ...
    end
  end
end
```
