This module performs interpolation on an input lattice
at a picked position, when a mouse button is pressed,
and outputs the value(s) of the lattice at that point.
Although it fires for all types of pick events, it only
updates the values for button down pick events.
Input pick port.
Input lattice. It can be of any primitive type, any
coordinate type and any vector length.
Output value(s) at the picked point. For multiple valued
lattices (nDataVar > 1) the values are separated by spaces.
If the picked point is outside the coordinate space of the
lattice, an error message is sent to the module's standard output.
