=====discrete Keyword 2 Phase 2=====
power set

====Definition====
A power set is a set of all the subsets.  This set includes the empty set and the set itself.  for example if we took a set called t={x,y}.  
All the subsets would be:

{}
{x}
{y}
{x,y}

Thus the power set of this would include:

P(t)={{}, {x}, {y}, {x, y}}
