Define Special Linked Ordered Sets.
New style
members and weights may be stored in SOS object
This is for y and x*f(y) and z*g(y) etc

Set bounds to fix the variable at the current (integer) value.
Given an integer value, set the lower and upper bounds to fix the variable. Returns amount it had to move variable.
