Detailed Description

UCLASS(Blueprintable, meta = (BlueprintSpawnableComponent), ClassGroup = (VRExpansionPlugin))

A scene component that can sample its positions to record / track VR gestures Core code is from https://social.msdn.microsoft.com/Forums/en-US/4a428391-82df-445a-a867-557f284bd4b1/dynamic-time-warping-to-recognize-gestures?forum=kinectsdk I would also like to acknowledge RuneBerg as he appears to have used the same core codebase and I discovered that halfway through implementing this If this algorithm should not prove stable enough I will likely look into using a more complex and faster one in the future, I have several modifications to the base DTW algorithm noted from a few research papers. I only implemented this one first as it was a single header file and the quickest to implement.
