/**Function*************************************************************
Synopsis [Create the mapping manager.]
Description [The number of inputs and outputs is assumed to be
known is advance. It is much simpler to have them fixed upfront.
When it comes to representing the object graph in the form of
AIG, the resulting manager is similar to the regular AIG manager,
except that it does not use reference counting (and therefore
does not have garbage collections). It does have table resizing.
The data structure is more flexible to represent additional
information needed for mapping.]
