Code Overview needs to be updated

[butlerpd]

The wiki entry Getting Started for developers, under Code overview, currently points to a PDF in the documents repo named SasViewDevIntro.pdf. However this is now quite outdated. Examples include reference to Trac and Jira that are no longer used as well as pointing to src/sas/sasgui that was always incorrect and at this point no longer exists. Also Jenkins will soon (we hope) be deprecated and it is not clear that we should continue in the intro to point to 4.x conda setup, particularly since it does not work at the moment with python 2.7. We could try to move that to 3.0 but the question of whether it should be part of the intro to new developers remains.

Particularly for something like this which will need regular updating, using a pdf only is probably not appropriate as one would want something more easily editable by the team. It is probably not possible to do this directly in the wiki so including an odtf file under version control would be best. but at the least a ppt that most folks can edit would be helpful.
