This applies a force and/or torque to a body according describe by arrays contained in a Storage The source of the Storage may be experimental sensor recording or user generated data.
The Storage must be able to supply (1) array of time, (3) arrays for the x,y,z, components of force and/or torque in time. Optionaly (3) arrays for the point of force application in time. This Force must identify a force identifier (e.g. Force1.x Force1.y Force1.y) may be individual labels for force components but they are collectively identified (as "Force1"). Similarly, identifiers for torque and point are expected.
If an identifier is supplied and it cannot uniquely identify the quantity (force, torque, point) in the Storage an Excpetion is thrown.
An ExternalForce must apply either a force or a torque so both identifiers cannot be empty.
