/**
* A base class fragment to be used with ChartsActivity. The fragment can supply
* a title to be displayed in the activity by returning non-null in #getTitle()
* Broadcast events can be received by overriding #onReceive(Context,Intent).
* The chart can be refreshed by calling #refresh()
* Implement refreshInBackground(DBHandler, GBDevice) to fetch the samples from the DB,
* and add the samples to the chart. The actual rendering, which must be performed in the UI
* thread, must be done in #renderCharts().
* Access functionality of the hosting activity with #getHost()
* <p/>
* The hosting ChartsHost activity provides a section for displaying a date or date range
* being the basis for the chart, as well as two buttons for moving backwards and forward
* in time. The date is held by the activity, so that it can be shared by multiple chart
* fragments. It is still the responsibility of the (currently visible) chart fragment
* to set the desired date in the ChartsActivity via #setDateRange(Date,Date).
* The default implementations #handleDatePrev(Date,Date) and #handleDateNext(Date,Date)
* shift the date by one day.
