title: How can I display the function name in vim-airline?
body: <p>I'm using the <code>ctags</code> vim plugin to have the name of the current C function (=where the cursor is) displayed in the status line.</p>
  
  <p>Today I installed the vim-airline plugin. Fancy, but the C function name is no longer displayed in the status line. There is lots of room for more text. Is there a way to make <code>ctags.vim</code> and <code>airline</code> coexist or some other technique to show the function name somewhere in the status line like ctags does?</p>
  
  <p>I searched the <code>:help airline</code> for <code>function</code> but that did not answer my question.</p>
