title: How to create a plugin for handsontable
body: <p>I want to create a plugin for handsontable and copied the removeRow files in extenstions subfolder to <em>jquery.handsontable.myPlugin.[js|css]</em>. 
  In those files I renamed every occasion of <strong>removeRow</strong> to <strong>myPlugin</strong> and <strong>RemoveRow</strong> to MyPlugin.</p>
  
  <p>In the table definition I have added <code>myPlugin: true</code>.</p>
  
  <p>But the plugin (which still should show the column with button to delete the rows) is not called.</p>
  
  <p>I have added a <code>console.log("init (removeRow)")</code> and <code>console.log("init (myPlugin)")</code>
  in both plugins in the init().
  It seems that only the <em>removeRow</em> plugin is called bun not <em>myPlugin</em>.</p>
  
  <p>Do I have to register the plugin somehow to handsontable?
  I assumed placing both file into the extension folder should be sufficient.</p>
  
  <p>Many Thanks</p>
