/**
 * TTCC layout format consists of:
 * - **t**ime,
 * - **t**hread, 
 * - **c**ategory and
 * - nested diagnostic **c**ontext information
 * 
 * Each of the four fields can be individually enabled or disabled. The time 
 * format depends on the **dateFormat** used. If no dateFormat is specified 
 * it defaults to '%c'. See php {@link PHP_MANUAL#date} function for details.
 *
 * ## Configurable parameters: ##
 * 
 * - **$threadPrinting** (boolean) enable/disable pid reporting.
 * - **$categoryPrefixing** (boolean) enable/disable logger category reporting.
 * - **$contextPrinting** (boolean) enable/disable NDC reporting.
 * - **$microSecondsPrinting** (boolean) enable/disable micro seconds reporting 
 *   in timestamp.
 * - **$dateFormat** (string) sets the date format.
