Fixed a bug in the contact reporting APIs that may have caused incorrect values to be returned as contact forces on the GPU
Omni.Anim.People:

Backward compatible API update to CortexObjectsRos and CortexSimObjectsRos to fix hard coded in_coords.
Isaac Replicator
Simplified SD Recorder code using newer Replicator API functionalities
Added a basic UI for Composer to view/preview the generated scenarios
Omni.isaac.extension_templates
UI tool under Isaac Utils -> Generate Extension Templates to download python extension templates locally
Extension Templates significantly reduce the complexity of building a custom UI application in Isaac Sim.

Replaced InverseKinematicsSolver(BaseController) object with ArticulationKinematicsSolver
Renamed MotionGenerator to ArticulationMotionPolicy
Extracted methods from MotionPolicy to form a WorldInterface class. This has no functional effect on any code outside MotionGeneration
Obstacles are now marked as static explicitly when added to MotionPolicy
Fixed typo in interface_config_loader.py.
modified default RmpFlow configs have fewer updates per frame (10 was unnecessary) and to not ignore robot state updates by default
updated golden values in tests as a direct result of config change
Restructured MotionGeneration extension to place emphasis on MotionPolicy over MotionGeneration. The user is now expected to interact directly with a MotionPolicy for adding/editing obstacles, and setting targets. MotionGeneration is a light utility class for interfacing the simulated USD robot to the MotionPolicy (get USD robot state and appropriately map the joint indeces).
RmpFlowController -> MotionPolicyController:
The RmpFlowController wrapper that was used to interface Core examples with RmpFlow has been expanded to wrap any MotionPolicy
omni.isaac.motion_generation/policy_configs -> omni.isaac.motion_generation/motion_policy_configs: changed folder containing config files for MotionPolicies to be named “motion_policy_configs” to leave room for future interfaces to have config directories
Path to RmpFlow: omni.isaac.motion_generation.LulaMotionPolicies.RmpFlow -> omni.isaac.motion_generation.lula.motion_policies.RmpFlow
Updated MotionGeneration to use Core API to query prim position and control the robot
Fixed
