7  Synopsis    [Multi-valued variables.]
8
9  Description [This package contains the data structure for multi-valued
10  variables. For each variable in a BLIF-MV network, this structure is
11  created. The information contained in this structure for a variable is
12  the name, the type (PI,PO,PS,NS etc), the range size, the list of symbolic
13  value names if any, and the encoding of a variable. Any variable can be
14  categorized either to an enumerative variable or a symbolic variable.
15  Enumerative variables are variables which take values from [0,...,n-1\],
16  where n is the range of the variable, while symbolic variables are
17  variables which take symbolic values (e.g., [red,blue,green\]). ]
