The inverse function is only callable with doubles because the inverse might fail if called for a point out of range, and it is unclear what should happen if the inverse were to succeed for some points in a DataVector but fail for other points. | |

Translation map defined by \(\vec{x} = \vec{\xi}+\vec{T}(t)\).
The map adds a translation, \(\vec{T}(t)\), to the coordinates \(\vec{\xi}\), where \(\vec{T}(t)\) is a FunctionOfTime.
