LocalExplorer.cpp

/*
 * This class represents a tree view of the local file system
 * It is a single widget which encompasses an address bar and the treeview
 *
 * A table is setup with a model of the local file system. Directory changes are handled by
 * implementing the doubleclick event on a row. There is also an addressBar object,
 * of the AddressBar class
 * This object communicates with the table+model to point out back/forward presses, and
 * address edit area updates.
 *
 * The class always stores a string of the current directory to be used when communicating
 * to the address bar
