*Background thread:
** performs work
** indicates progress
* UI Thread:
** does setup
** publishes intermediate progress
** uses results
AsyncTask is a generic class, it takes 3 parameters:
''AsyncTask<Params,Progress, Result>''
* params - type used in background work
* progress - type used when indicating progress
* result - type of result
AsyncTask runs as follows:
* void onPreExecute() (UI Thread)
* Result doInBackground(Params...) (background thread)
** this method may call publishProgress(Progress...)
** this call will result in an invoke of ''onProgressUpdate(Progress...) on the UI Thread
* void onPostExecute(Result) (UI Thread)
