/**
* BidirectionalTool let you draw annotations that measures the length and
* width at the same time in `mm` unit. It is consisted of two perpendicular lines and
* a text box. You can use the BidirectionalTool in all planes even in oblique
* reconstructed planes. Note: annotation tools in cornerstone3DTools exists in the exact location
* in the physical 3d space, as a result, by default, all annotations that are
* drawing in the same frameOfReference will get shared between viewports that
* are in the same frameOfReference.
*
* The resulting annotation's data (statistics) and metadata (the
* state of the viewport while drawing was happening) will get added to the
* ToolState manager and can be accessed from the ToolState by calling getAnnotations
* or similar methods.
*
* ```js
* cornerstoneTools.addTool(BidirectionalTool)
*
* const toolGroup = ToolGroupManager.createToolGroup('toolGroupId')
*
* toolGroup.addTool(BidirectionalTool.toolName)
*
* toolGroup.addViewport('viewportId', 'renderingEngineId')

* toolGroup.setToolActive(BidirectionalTool.toolName, {
* bindings: [
