///Usage
///-----
// The following example illustrates how to use a 'baltzo::DataFileLoader' to
// load the Zoneinfo time zone data for a time zone.
//
///Prologue: Create a Example Data File
/// - - - - - - - - - - - - - - - - - -
// We need to create one time zone data file on which to operate in the
// remainder of the example. In practice, clients should *not* generate data
// files in this manner. Data files are typically created using the 'zic'
// compiler -- a publicly available tool provided as part of the standard
// Zoneinfo distribution (see 'http://www.twinsun.com/tz/tz-link.htm') -- and
// deployed in a standard directory location (see
// 'baltzo_defaultzoneinfocache').
//
// First we define static binary data for "Asia/Bangkok" (chosen because it is
// relatively small):
