- Added global tasks which are run at tree level similar to evals (will replace evals)
- allows initial state selection to rely in calculated data (e.g. world conditions)
- allows better reuse of existing logic
- Call evaluator stop in reverse order
- Use some uses of mutable instanced structs
- Copy bindings along with ST nodes
- Remove bindings when removing a ST node, so that undo can restore them

- Removed gated delay (transition will be delayed until it has been "pressed" for N seconds)
- Delay now triggers after the delay duration has passed (single trigger, not "pressed", works with events too)
- Added random variation for the delay
- Tick/Event transitions has precedence over completion transitions (that is, they are handled before completion transitions)
- Removed delay and blocking from completion transitions
- Small improvements for transitions UI

- Updated add button to new positive button style
- Change the add-state logic to add to root or subtrees if context is present (e.g. add after)

- converted mass smart object and movement tasks to use struct ref

- Changed FStateTreeHandle to FStateTreeStateHandle, used only for indexing states
- Added uint16 and uin8 index types, which can represent invalid index (aka INDEX_NONE)
- Changed indices that can be optional to the index types above
- Added validation and error loggic when index types overflow during compile
- Removed 2 indirections (in common case) and halved the memory usage of property copies

- Commented and cleaned up the members of UStateTree a bit
- Changed StateTree Node storage to FInstancedStructArray (contiguous memory)
- Changed StateTree SharedData to FInstancedStructArray
- Changed StateTree instance data to use FInstancedStructArray
- StateTree statistics shows estimated mem usage per state and max for tree (heaviest linked chain)
- Added explicit bLinked state for UStateTree
- Cleaned up UStateTree::ResetCompiled()/ResetLinked()
- Changed StateTree execution context to allocate task instance data on Start() and EnterState()
- StateTree tick uses execution order counters to access the instance data instead of compile time specific index

[CL 20221385 by mikko mononen in ue5-main branch]
- Separated condition instance data into a shared instance data (mutable but no persistent state)
- Made BP TestCondition() const, conditions should not hold state
- Added macro to define runtime data POD for faster init
- Added custom serialization version for UStateTree, older assets need recompile
- Updated memory reporting to be a bit more accurate, separated shared and unique data

[CL 20134929 by mikko mononen in ue5-main branch]
- Added specific "subtree" states which can be linked to via a "linked" state
- Subtrees can only bind data back to the their root state (or tree "global" data)
- Added property bag based parameters to subtree and linked states
- Update (transient) property bag structs before resolving property paths
- Linked states reflect their parameters from the state they link to
- Added property binding to and from parameters
- Relaxed the property binding to fail if the source data is not available
- Allow enter conditions to bind to tasks, and fail the expression if trying to access unaccessible data
- Added icon for linked and subtree states
- Added source type for all binding source structs
- Added UStateTreeEditorData::VisitHierarchy to simplify iterating over all states

+ Added StateTree parameters usable for data bindings and that could be overriden on context initialization by a StateTreeReference
+ Added StateTreeReference struct to hold a reference to a StateTree asset along with a list of values to parameterized the tree.
+ Added named external data items that are defined bt the Schema and for which values must be provided at runtime through the execution context.
+ Added delegate OnPostCompile after successful compilation. The StateTreeReference listens to it to validate its parameters
+ EditorData now contains its own version of the schema and parameters. On successful compilation they are copied over the StateTree own properties.
