docs: Androlog Init Method. This method loads the Androlog Configuration from:
  <ol>
  <li><code>/SDCARD/fileName</code> if the file name if not
  <code>null</code></li>
  <li><code>/SDCARD/Application_Package.properties</code> if the file name
  is <code>null</code> and context is not <code>null</code></li>
  <li><code>Application_Assets/fileName</code> if the file name if not
  <code>null</code> and the context is not <code>null</code></li>
  <li><code>Application_Assets/Application_Package.properties</code> if the
  file name is <code>null</code> and the context is not <code>null</code></li>
  </ol>
  The first found file is used, allowing overriding the configuration by
  just pushing a file on the SDCard. Passing <code>null</code> to both
  parameters is equivalent to the case 2. If the lookup failed, the logging
  is disabled.
  
  @param context
  the application context
  @param fileName
  the file name
