[ Timer ] section
==================================================

The timer function can be defined in this section. 
The timer controls the time of each particle when 

#. a particle comes into specified region (in) [#]_

#. a particle goes out specified region (out)

#. a particle takes scattering in specified region (coll)

#. a particle reflects back on a certain boundary of the region (ref).

You can set the time to be zero(-1), stopped(1) or nothing(0).

.. [#] The counter also counts when a source particle is generated within the region specified by ``in``. This specification was not written in the manual, but has been included since the counter function was implemented. If you have performed a calculation that generates sources within the region specified by ``in``, please confirm it.

The format is as follows.

.. code-block:: text

  [ Timer ]
    reg   in    out   coll    ref
    1     0     -1    0       0
    11    1      0    0       0
    ...   ...   ...   ...     ...
    ...   ...   ...   ...     ...

If you want to replace the order of region number (reg), (in), (out), (coll), and (ref), set as reg coll in out  ref. 
You can use the skip operator non.
At least one must be defined in the in out coll ref. 
If nothing is defined, it is assumed no action. 

You can use the format ( { 2 - 5 } 8 9 )}, and you can use the lattice and universe style as ( 6 < 10[1 0 0] < u=3 ). 
But you need to close a value by (  )  if it is not a single numeric value.
