/**
 * ### Context: Get
 *
 * Returns the current application context which may include possible sub-contexts.
 * The application context can be 'Production', 'Development' or 'Testing'.
 * Additionally each context can be extended with custom sub-contexts like: 'Production/Staging' or ' Production/Staging/Server1'.
 * If no application context has been set by the configuration, then the default context is 'Production'.
 *
 * #### Note about how to set the application context
 *
 * The context TYPO3 CMS runs in is specified through the environment variable TYPO3_CONTEXT.
 * It can be set by .htaccess or in the server configuration
 *
 * See: http://docs.typo3.org/typo3cms/CoreApiReference/ApiOverview/Bootstrapping/Index.html#bootstrapping-context
