title: Filter rows where column value ends with a set of patterns
body: <p>I have a data set as follows</p>
  
  <pre><code>File_name     Folder
  ord.cpp        1
  rod.ibo        1
  ppol.h         2
  lko.cpp        3
  rto.cp         3
  tax.mo         2
  t_po..lo.cpp   4
  </code></pre>
  
  <p>I need to subset this data set so that only rows where File_name ends with ".cpp" or ".h" is present in the data set</p>
