/**
* @brief A navigation bar widget for ProjectExplorer's Icon and List views
*
* Unlike the Tree view, Icon and List don't follow a hierarchical view of information. This means there is no direct
* way of navigating in and out of folders in those view types. We solve this in two ways:
*
* * Double clicking a Folder in those views will enter that folder
* * This navigation bar offers a "directory up" button for leaving a folder
*
* This navbar also provides an icon size slider for those views (between kProjectIconSizeMinimum and
* kProjectIconSizeMaximum) as well as text that's intended to be set to the current Folder's name (or
* empty for the root folder).
*
* This widget does not actually communicate to Project or ProjectExplorer classes. It is simply UI widgets that are
* intended to be connected in ways that do. This is the primarily responsibility of ProjectExplorer.
*
* By default, the directory up button is disabled (assuming root folder), the text is empty, and the icon size slider
* is set to kProjectIconSizeDefault.
