Behavior when output_vtk is blank was not documented in the docstring (it was demonstrated in examples, however)
output_vtk='' is a good, meaningful default, the value used in the examples, and the default value for similar arguments... so just make it the default value.
input_values_vtk='' is the default, but if you use that default you get an error. This should set input_values_vtk = input_indices_vtk, as implied by downstream code in explode_scalars; I simply implemented the two lines to check & set.
Testing:
I tested these all manually (with defaults, and specifying params).
