[GSoC] Week 6 Report

Hi,

Here is the week 6 Report:
* Worked on patch [1] which was pushed to remote this week
    + Implemented InitGalleryTheme() and DestroyGalleryTheme() to handle
the lifecycle of SotStorage object
* Removed long chains from the code I wrote
    + e.g.,
pGalleryTheme2->pThm->getGalleryBinaryEngine()->GetSvDrawStorage() from the
code and improved it by implementing new functions in GalleryThemeEntry
    + Two chains were removed last week, a lot more to come in the next
patch
* Resumed working on refactoring more functions
    + Submitted [2] which is still WIP
    + GetModel() and GetModelStream() were refactored
    + implCreateUniqueURL() and ImplGetURL() are now in galmisc.cxx, which
is the right place for now..

To-do tasks for this week would be:
* Finish further refactoring on InsertModel(), InsertModelStream(),
InsertObject()
* GalleryTheme class should be done by the end of the week.

Warm Regards,
Aditya Sahu
