/**
 * Java side of the Browser Context: contains all the java side objects needed to host one
 * browing session (i.e. profile).
 * Note that due to running in single process mode, and limitations on renderer process only
 * being able to use a single browser context, currently there can only be one AwBrowserContext
 * instance, so at this point the class mostly exists for conceptual clarity.
 *
 * Obtain the default (singleton) instance with  AwBrowserProcess.getDefaultBrowserContext().
