+/**
+ * Provides a parser and evaluator for unix-like cron expressions. Cron
+ * expressions provide the ability to specify complex time combinations such as
+ * "At 8:00am every Monday through Friday" or "At 1:30am every
+ * last Friday of the month".
+ * <P>
+ * Cron expressions are comprised of 6 required fields and one optional field
+ * separated by white space. The fields respectively are described as follows:
+ *
+ * <table cellspacing="8">
+ * <tr>
+ * <th align="left">Field Name</th>

+ * <P>
+ * The '*' character is used to specify all values. For example, "*"
+ * in the minute field means "every minute".
+ * <P>
+ * The '?' character is allowed for the day-of-month and day-of-week fields. It
+ * is used to specify 'no specific value'. This is useful when you need to
+ * specify something in one of the two fields, but not the other.
+ * <P>
+ * The '-' character is used to specify ranges For example "10-12" in
+ * the hour field means "the hours 10, 11 and 12".
+ * <P>
+ * The ',' character is used to specify additional values. For example
+ * "MON,WED,FRI" in the day-of-week field means "the days Monday,
+ * Wednesday, and Friday".
+ * <P>
+ * The '/' character is used to specify increments. For example "0/15"
+ * in the seconds field means "the seconds 0, 15, 30, and 45". And
+ * "5/15" in the seconds field means "the seconds 5, 20, 35, and
+ * 50". Specifying '*' before the '/' is equivalent to specifying 0 is
+ * the value to start with. Essentially, for each field in the expression, there
+ * is a set of numbers that can be turned on or off. For seconds and minutes,
+ * the numbers range from 0 to 59. For hours 0 to 23, for days of the month 0 to
+ * 31, and for months 1 to 12. The "/" character simply helps you turn
+ * on every "nth" value in the given set. Thus "7/6" in the
+ * month field only turns on month "7", it does NOT mean every 6th
+ * month, please note that subtlety.
+ * <P>
+ * The 'L' character is allowed for the day-of-month and day-of-week fields.
+ * This character is short-hand for "last", but it has different
+ * meaning in each of the two fields. For example, the value "L" in
+ * the day-of-month field means "the last day of the month" - day 31
+ * for January, day 28 for February on non-leap years. If used in the
+ * day-of-week field by itself, it simply means "7" or
+ * "SAT". But if used in the day-of-week field after another value, it
+ * means "the last xxx day of the month" - for example "6L"
+ * means "the last friday of the month". When using the 'L' option, it
+ * is important not to specify lists, or ranges of values, as you'll get
+ * confusing results.
+ * <P>
+ * The 'W' character is allowed for the day-of-month field. This character
+ * is used to specify the weekday (Monday-Friday) nearest the given day. As an
+ * example, if you were to specify "15W" as the value for the
+ * day-of-month field, the meaning is: "the nearest weekday to the 15th of
+ * the month". So if the 15th is a Saturday, the trigger will fire on
+ * Friday the 14th. If the 15th is a Sunday, the trigger will fire on Monday the
+ * 16th. If the 15th is a Tuesday, then it will fire on Tuesday the 15th.
+ * However if you specify "1W" as the value for day-of-month, and the
+ * 1st is a Saturday, the trigger will fire on Monday the 3rd, as it will not
+ * 'jump' over the boundary of a month's days. The 'W' character can only be
+ * specified when the day-of-month is a single day, not a range or list of days.
+ * <P>
+ * The 'L' and 'W' characters can also be combined for the day-of-month
+ * expression to yield 'LW', which translates to "last weekday of the
+ * month".
+ * <P>
+ * The '#' character is allowed for the day-of-week field. This character is
+ * used to specify "the nth" XXX day of the month. For example, the
+ * value of "6#3" in the day-of-week field means the third Friday of
+ * the month (day 6 = Friday and "#3" = the 3rd one in the month).
+ * Other examples: "2#1" = the first Monday of the month and
+ * "4#5" = the fifth Wednesday of the month. Note that if you specify
+ * "#5" and there is not 5 of the given day-of-week in the month, then
+ * no firing will occur that month. If the '#' character is used, there can
+ * only be one expression in the day-of-week field ("3#1,6#3" is
+ * not valid, since there are two expressions).
+ * <P>
+ * <!--The 'C' character is allowed for the day-of-month and day-of-week fields.
+ * This character is short-hand for "calendar". This means values are
+ * calculated against the associated calendar, if any. If no calendar is
+ * associated, then it is equivalent to having an all-inclusive calendar. A
+ * value of "5C" in the day-of-month field means "the first day included by the
+ * calendar on or after the 5th". A value of "1C" in the day-of-week field
+ * means "the first day included by the calendar on or after sunday".-->
+ * <P>
+ * The legal characters and the names of months and days of the week are not
+ * case sensitive.
+ *
+ * <p>
+ * <b>NOTES:</b>
+ * <ul>
+ * <li>Support for specifying both a day-of-week and a day-of-month value is
+ * not complete (you'll need to use the '?' character in one of these fields).
+ * </li>
+ * <li>Overflowing ranges is supported - that is, having a larger number on
+ * the left hand side than the right. You might do 22-2 to catch 10 o'clock
+ * at night until 2 o'clock in the morning, or you might have NOV-FEB. It is
+ * very important to note that overuse of overflowing ranges creates ranges
+ * that don't make sense and no effort has been made to determine which
+ * interpretation CronExpression chooses. An example would be
+ * "0 0 14-6 ? * FRI-MON". </li>
+ * </ul>
