* 1. MainMenu - The function prints menu.
* 2. GetUserRequest - The function gets a user request and performs search according this request.
* 3. FileNameRequested - The function returns file name from the user.
* 4. PathRequested - The function returns path from the user if the user chose option 2. If the user chose option 1 the path is C:\\ by default.
* 5. SearchAccessibleFiles - The function receives 2 parameters: filename and directory - path (where to search this file) and
* returns list of paths if there 1 or more and 0 if the file name not found;
* 6. InsertInToDB - The function inserts the result to the database (SearchFileDB) with a table name searchFileLog and columns:
* ID, seachPattern, seachPatternPath, searchDate, resultPatternPath.
