title: Save Pyomo model Variable
body: <p>I'm doing an optimization problem and after give the command:</p>
  
  <pre><code>results = solver.solve(model,tee=True)
  </code></pre>
  
  <p>I will have all my variables solved inside the model object. </p>
  
  <p>There is a way to save and load this model object?</p>
