Change the VTKM_CONT_EXPORT to VTKM_CONT. (Likewise for EXEC and EXEC_CONT.) Remove the inline from these macros so that they can be applied to everything, including implementations in a library. Because inline is not declared in these modifies, you have to add the keyword to functions and methods where the implementation is not inlined in the class.
