Philip Top 6b7f6a7480 Value initialization (#416) 
* work on the flags book chapter and making sure the values are initialized properly.

* Fix initialization of values used in flags or options

* update some formatting and more brace initialization

* update more formatting and fix a incorrect initializer

* more formatting and some error fixes

* more formatting

* Small formatting fix
