qLibc 2.4.0 Release

Hi all the qLibc developers

I'm pleased to announce qLib 2.4.0 Release.
This release includes a new vector implementation and improved unit tests.

Changes

• This version includes array-based new vector implementation.
• Previous version of list-based vector implementation was renamed to qgrow
• Improved unit tests. Now unit tests cover most of the containers.
• Typo error corrections and document improvements.

Thank you all
