Detailed Description

Tool to fit a trajectory using a set of two segments or a track and a segment as input.

The tool can be configured to fit either a straight line or all 5 parameters of the track.

For more details look at the mainpage of this package.

Declare a new Gaudi property.

Parameters
nameName of the property.
propertyObject holding the property value.
docDocumentation string for the property.

This is the generic version, for types that do not derive from SG::VarHandleKey. It just forwards to the base class version of declareProperty.
