 * - Stores each filename and path only once, using DataStore.
 *
 * User Interface:
 * changePath("/aPath");
 * addPattern("*.h");
 * search();
 *
 * Required Files:
 * ---------------
 * FileMgr.h, FileMgr.cpp, FileSystem.h, FileSystem.cpp,
 * DataStore.h, DataStore.cpp, Utilities.h, Utilities.cpp
 *
 * Build Process:
 * --------------
 * From the Visual Studio Developer's Command Prompt:
