TaskScheduler version 1.8.0 - added support for event completion signallingv1.8.0

 * Introduced option to compile with support for Status Rquests - ability to wait for and signal event completion
 * Moved all code to one header file allowing control at compile time via #define statments.

+/** This test demonstrates interaction between three simple tasks via StatusRequest object.
+ *  Task T1 runs every 5 seconds and signals completion of a status request st.
+ *  Tasks T2 and T3 are waiting on the same request (st)
+ *  Task T3 does not renew its interest in status request st, so it is only invoked once (first iteration)
+ *  Task T2 is invoked every time st completes, because it renews its interest in status of status request object st every iteration of T1
