commit before moving main articles code to topics article
moved ArticleActivity code to TopicsActivity and then overrode spinner-related methods in ArticleActivity to prevent any spinner from showing
Put main logic related to the article activities back into ArticleActivity and out of TopicsActivity because it makes more sense for only the spinner-related information to be in the class which implements spinners, and the functionality it builds on to be in another class (ArticleActivity)
Increased icon size, added zebra to the feeds list, added clean looking drop shadow to the articles list, and did away with the shitty old drop shadow that was there
fixed critical bug that caused topics to crash on navigation away from activity
fixed stability surrounding concurrent access by creating a WriteLockManager interface that handles locking and thread waiting to access DBs that are locked. Also implemented safe concurrent read & write access. Also fixed filtering on topics to work with 'all'
completed multi-textview spinner project with great success! It is now abstracted away in the base class NavigationDrawerWithSpinner
preparing for first git upload
added working link to github repository
