/// <summary>
/// The Template Pattern allows us to define a skeleton method - 'template methods' - for execution of a series of steps, with the possibility of relegating one or more steps to variant classes.
/// </summary>
/// <example>
/// Real life uses include...
/// - Setup-projects of various kinds, where an environment - any one - needs to be set-up through a number of steps, though accomodate minor local considerations such as physical location (ISS, anyone), selected battle-arena for a game, chosen user profile, so on and so forth.
/// - Security operations, where access rights and such are set up by a fixed mechanism, though possible to grant/revoke certain rights for certain individuals.
/// - Data exports, where data is gathered through a number of pre-defined steps but the last step, the actual persistence of data, may vary.
/// - Generally, all places where 'first this, then that, then this', i.e. we execute a number of predefined steps. Surprisingly many.
