converted checkedTimeResets() from two-pass logic that first computes the required size of SpanBuf to a single-pass that utilizes vector<SpanBuf> instead. Much cleaner and easier.
checkEvents() now allows for multiple characteristics to be updated by service->notify(). This change included the use of vector<SpanBuf> to dynamically create the the temporary storage needed. To do: re-work similar routines to use vector<SpanBuf> instead of needing to perform two passes each time to gauge size of SpanBuf array needed.
creating code to allow for multiple characteristics to be updated within event() call. To Do: define anogther sensor that supports multiple characteristics. also need to check that "new SpanEvent" works as expected from within a defined service.
