-/*

- * MinimalUserProfiles sample:

- * This is an example that demontrates how to retrieve and listen to changes to 

- * the states Current Profile Name and Profiles, and how to change the Current

- * Profile.

- * 

- * (It is written in mostly very C-style C++, to make it similar to the other

- * minimal samples but still make use of std::vector and std::string. Using those

- * makes the implementation more straightforward when handling the Profile state 

- * which is very dynamic in nature: an unknown number of profile name entries of 

- * unknown size.) 

- *

- * Known limitation: this sample only works correctly for up to 10 profiles. It

- * will list all profiles, but the input will only read one digit, so 9 will be

- * the highest selectable index.

- *
