title: search missing values in object array
body: <p>I have an array that I bind to a javascript based pivot table. The data is missing some of the require rows. So, I need to find which data may be missing and inject it in my object array.</p>
  
  <p>The data is in the format:<br>
  <strong>Person, WorkType, month, value</strong><br>
  Me, Baseline, 10, 12.00<br>
  Me, Planned, 10, 12.00<br>
  Me, Actual, 10, 6.00<br>
  You, Planned, 10, 12.00  </p>
  
  <p>I am pivoting rows on the person and type columns. However as you see here Person "You" does not have at least one record for Baseline or Actual and I need to figure out which data is missing and inject at least one row for the missing work type so my pivot view is uniform. </p>
  
  <p>Any good idea's how to evaluate my object array and inject the missing row(s)?</p>
