Split A AD valvector
####################
Split one AD<valvector> into a vector of AD<valvector> each with size one.

Syntax
******
| valvector_ad_split *asplit*
| *asplit( *ax* , *ay_vec* )

m
*
We use *m* to denote *ay_vec* .size()

ax
**
This CppAD::AD<valvector> is ``const`` and passed by reference.
The size *ax*.size()  must be equal to one or *m*

ay_vec
******
This is a :ref:`SimpleVector-name` with elements of type CppAD::AD<valvector>
and is passed by reference.
The size of *ay_vec* is not changed.
Upon return, for *i* = 0 , ... , *m* - 1 ,
the size *ay* [ *i* ].size() is one and::

   ay[i][0] = ax[i]
