Combine get_value(..)  function and get_voxel_time_points(...) function into a new one called get_value(...),add a "time_course" parameter to determine whether to return the points. The get_voxel_value(...) has been deleted also.
Add time_course parameter in get_current_value(...) function explicitly, just like get_current_value(..., time_course=True).
