/***
    eeprom_iteration example.
    
    A set of example snippets highlighting the
    simplest methods for traversing the EEPROM.
    
    Running this sketch is not necessary, this is 
    simply highlighting certain programming methods.

  /***
    Iterate the EEPROM using a C++11 ranged for loop.
    
    This version of the loop is best explained in the example 'eeprom_pointer'
    as this kind of iteration uses pointers rather than an index/integer.
    
    !! Note: C++11 is not yet enabled by default in any IDE version.
       Unless you manually enable it, this sketch will not compile.
       You can comment the loop below to verify the non C++11 content.
