title: Where is the module sublime_api?
body: <p>Some ST2 plugins have references to module <code>sublime_api</code> in their Python files. I've found such text in several github.com projects.</p>
  
  <p>What is this <code>sublime_api</code> module? Where can I see it and/or where does it come from? Maybe it's somehow sitting in memory only. What is background of this module, seems it's important for ST2 plugins.</p>
  
  <p>So far I found info only about <code>sublime</code> and <code>sublime_plugin</code> modules.</p>
