/**
* 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:

* <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 0 to 11 (JAN to DEC). 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". You can also specify an offset
* from the last day of the month, such as "L-3" which would mean the third-to-last
* day of the calendar month. <i>When using the 'L' option, it is important not to
* specify lists, or ranges of values, as you'll get confusing/unexpected results.</i>
* <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 "
