title: Group column from CSV file and concatenate values of another column
body: <p>I am just getting started with PowerShell and can not find an answer to this anywhere.<br>
  Trying to write a script that imports a CSV file and searches through the file to see if any names are the same. If the names are the same I want to write all of those values together on the same line and only show the name once.</p>
  
  <p>For example:</p>
  
  <pre><code>Name   Number    
  Tom    1  
  Tom    4  
  Bill   3  
  Dave   2  
  Dave   5   
  Dave   6  
  </code></pre>
  
  <p>With this output:</p>
  
  <pre><code>Tom- The number(s) associated with this person is/are: 1/4  
  Bill- The number(s) associated with this person is/are: 3  
  Dave- The number(s) associated with this person is/are: 2/5/6
  </code></pre>
