+ * Welcome!
+ * Your start-up's BA has told marketing that your website has a large audience in Scandinavia
+ * and surrounding countries. Marketing thinks it would be great to welcome visitors to the site in
+ * their own language. Luckily you already use an API that detects the user's location, so this is an
+ * easy win.
+ * <p>
+ * The Task
+ * <p>
+ * Think of a way to store the languages as a database (eg an object). The languages are listed below
+ * so you can copy and paste!
+ * Write a 'welcome' function that takes a parameter 'language' (always a string), and returns a
+ * greeting - if you have it in your database. It should default to English if the language is not
+ * in the database, or in the event of an invalid input.
+ * The Database
+ * <p>
+ * english: "Welcome",
+ * czech: "Vitejte",
+ * danish: "Velkomst",
+ * dutch: "Welkom",
+ * estonian: "Tere tulemast",
+ * finnish: "Tervetuloa",
+ * flemish: "Welgekomen",
+ * french: "Bienvenue",
+ * german: "Willkommen",
+ * irish: "Failte",
+ * italian: "Benvenuto",
+ * latvian: "Gaidits",
+ * lithuanian: "Laukiamas",
+ * polish: "Witamy",
+ * spanish: "Bienvenido",
+ * swedish: "Valkommen",
+ * welsh: "Croeso"
+ * <p>
+ * Possible invalid inputs include:
+ * <p>
+ * IP_ADDRESS_INVALID - not a valid ipv4 or ipv6 ip address
+ * IP_ADDRESS_NOT_FOUND - ip address not in the database
+ * IP_ADDRESS_REQUIRED - no ip address was supplied
