it will write_output() after each step. The data_arrays along with
the current_time_stamp must be set in order to write_output()

current_time_stamp. This is the time_stamp associated with 0-th
step so initial conditions for data arrays

standard array_types attribute. The data_arrays are initialized and
appended based on the values of array_types attribute

array_types and checks to see if there is an associated initializer
in each Spill. If a corresponding initializer is found, it gets the
array_types from initializer and appends them to its own list. For
