In some cases that SERVER_POST was not defined an notice was rose that
by checking it ti see wether it is set or not we can avoid getting any
notices.
Rastgo Framework core/bootStrap.php file is loaded insite the
Tests/bootStrap.php file so that when ever constants that is defined in
core/bootStrap is used in framework's libraries they can be accessed
when executing libraries using pphunit for testing testcases and then
there won't be any kind of error related to undefined constants which
is defined in core/bootStrap file.
Loading bootStrap file of the framework which some constant were defined in it were required to use them in testing some libraries that were coded not properly (hard coded) so by refactoring and loose coupling that the issue solved and this file is no longer required.
Translator library refactored with some changes.

Some new methods added to this library in order to enhance the
functionality of the library for what is it doing.

Two methods setDefaultLang and setLangFileExtension is deprecated now
because of their name which was not clear in indicating that what they
are exactly doing and programer advised to user other methods for same
purposes. (language and languageFileExtention respectively ).

This library is independant of Rastgo-Framework now and its possible to
use it out of framework.

Till now languages folder was harde coded in class which it is solved
now and programer has to define where he/she has put languages (address
		of root folder) by languagesFolder method in order to get this
library work.

Test cases are written for this library and are located in Tests folder
in root of the framework.
For throwing exception inside of the Translator library this class is
used rather than being dependant on Rastgo-Framework's log functionality
or using general Exception which is now allowed in test units by
phpunit.
Test cases (written in phpunit) for Translator library.
By refactoring Translator library this folder and files were unnecessary
so were deleted.
Previously translator library was used in controller to demonstrate how does it work. But waa not needed any more and removed.
