// 1.    When defining a culture, all fields are required except the ones stated as optional.
// 2.    You can use Globalization.extend to copy an existing culture and provide only the differing values,
//       a good practice since most cultures do not differ too much from the 'default' culture.
//       DO use the 'default' culture if you do this, as it is the only one that definitely
//       exists.
// 3.    Other plugins may add to the culture information provided by extending it. However,
//       that plugin may extend it prior to the culture being defined, or after. Therefore,
//       do not overwrite values that already exist when defining the baseline for a culture,
//       by extending your culture object with the existing one.
// 4.    Each culture should have a ".calendars" object with at least one calendar named "standard"
//       which serves as the default calendar in use by that culture.
// 5.    Each culture should have a ".calendar" object which is the current calendar being used,
//       it may be dynamically changed at any time to one of the calendars in ".calendars".

// To define a culture, use the following pattern, which handles defining the culture based
// on the 'default culture, extending it with the existing culture if it exists, and defining
// it if it does not exist.

    // specific to a region. For example, the culture "es" is the generic
    // Spanish culture, which may be a more generalized version of the language
    // that may or may not be what a specific culture expects.

    // neutral, generic culture information for the language it is using.
