title: Remove the slide count from Beamer footer
body: <p>I would like to remove the slide count (e.g., <code>SLIDE_NUMBER / TOTAL_SLIDES</code>) from the footer (footline) of a Beamer presentation, without removing the footer entirely. I am using the Boadilla theme, which uses the <code>infolines</code> outer theme. In the <code>beamerouterthemeinfolines.sty</code> file, we find the following definition for the footline:</p>
  
  <pre><code>\defbeamertemplate*{footline}{infolines theme}
  {
    \leavevmode%
    \hbox{%
    \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{author in head/foot}%
  \usebeamerfont{author in head/foot}\insertshortauthor~~(\insertshortinstitute)
    \end{beamercolorbox}%
    \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{title in head/foot}%
  \usebeamerfont{title in head/foot}\insertshorttitle
    \end{beamercolorbox}%
    \begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,right]{date in head/foot}%
  \usebeamerfont{date in head/foot}\insertshortdate{}\hspace*{2em}
  \insertframenumber{} / \inserttotalframenumber\hspace*{2ex} 
    \end{beamercolorbox}}%
    \vskip0pt%
  }
  </code></pre>
  
  <p>I need to essentially redefine this outer theme such that it doesn't have the <code>\insertframenumber{} / \inserttotalframenumber\hspace*{2ex}</code> in it, or otherwise define a new outer theme that inherits everything else from the infolines theme. How can I do this?</p>
