N-body case study

[martinjonsson01]

Reason

To have a real-world reason to implement features in the engine, we will develop an N-body simulation using the engine.

Requirements

• An N-body simulation is implemented in RECS
• There is intra-system parallelization:
  • The positions of all entities are updated concurrently
  • The accelerations of all entities are updated concurrently
• The bodies are rendered visually

Dependencies

• Allow systems to access components from multiple entities at once #50
• Rendering system #61
