/**
 * A {@code MidiFileFormat} object encapsulates a MIDI file's type, as well as
 * its length and timing information.
 * <p>
 * A {@code MidiFileFormat} object can include a set of properties. A property
 * is a pair of key and value: the key is of type {@code String}, the associated
 * property value is an arbitrary object. Properties specify additional
 * informational meta data (like a author, or copyright). Properties are
 * optional information, and file reader and file writer implementations are not
 * required to provide or recognize properties.
 * <p>
 * The following table lists some common properties that should be used in
 * implementations:
 *
 * <table class="striped">
 * <caption>MIDI File Format Properties</caption>
 * <thead>
 *   <tr>
 *     <th scope="col">Property key
