  10  * data and parameter space followed by two lines indicating
  11  * the number of existential variables and parameters respectively.
  12  * The first lines starts with "E ", followed by a number.
  13  * The second lines starts with "P ", followed by a number.
  14  * These two lines are (optionally) followed by the names of the parameters.
  15  * The polytope is in PolyLib notation.
