Lagrangian Coherent Strucutres (LCS) Filter for VTK-m

The new filter vtkm::filter::LagrangianStructures is meant for Finite Time Lyapunov Exponent (FTLE) calculation using VTK-m. The filter allows users to calculate FTLE in two ways

  1. Provide a dataset with a vector field, which will be used to generate a flow map.
  2. Provide a dataset containing a flow map, which can be readily used for the FTLE field calculation.

The filter returns a dataset with a point field named FTLE. Is the input is strucutred and an auxiliary grid was not used, the filter will add the field to the original dataset set, else a new structured dataset is returned.
