Detailed Description

Offset

Enables user to define a placement, either in global coordinates or in the coordinate system of the previously placed object

Parameters

_end_position	final position of the offset
_end_direction	normal vector to entry face
_is_local	parameter is True if everything is in the coordinate system of the last placed object. It is expected that everything will be in a local coordinate system before tracking begins (this is expected by, for example, Ring). This is expected to be set by the visit function in e.g. ParallelCyclotronTracker.
geometry	the geometry that RingSection uses to do displacements This has to be a pointer because SRotatedGeometry does not have an defined assignment op. SRotatedGeometry does not have a assignment op because BGeometryBase does not have an assignment op... and there is no way (I think) to reassign a previously assigned variable in C++ without using =
wrappedGeometry	Something to do with the reference handling in SRotatedGeometry - looks like it doesn't make a copy but holds a reference, so unless I keep that alive in Offset I get memory errors (seg fault) bends() and operator==(...) use float_tolerance when evaluating equality between doubles. conversion factor from user interface to get to mm

WARNING: this object uses a default aperture that is large. It will screw up any calculation based on aperture (e.g. wakefields etc)
