merge: Extract scheduler from simulation coroutine dispatcher (#106)
This pull request extracts the scheduler from the `SimulationCoroutineDispatcher` into
a separate `SimulationScheduler` class which allows users to re-use the scheduler
between different coroutine dispatchers.
We implement the `SimulationScheduler` in Java, removing the explicit dependency on
Kotlin or `kotlinx-coroutines`. The scheduler uses a separate specialized priority queue
implementation that eliminates allocation in the hot path of the simulator.
## Implementation Notes :hammer_and_pick:
* Add Java-based simulator core
* Use SimulationScheduler in coroutine dispatcher
* Rename runBlockingSimulation to runSimulation
## External Dependencies :four_leaf_clover:
* N/A
## Breaking API Changes :warning:
* The Kotlin API for simulation has been moved to `org.opendc.simulator.kotlin`.
* `runBlockingSImulation` renamed to `runSimulation`
