/* buildDate does all the real work.It takes a date string and format string,
 tries to match the two up, and returns a Date object (with the supplied date
 string value).If a date string doesn't contain all the fields that a Date
 object contains (for example, a date string with just the month), all
 unprovided fields are defaulted to those characteristics of the current
 date. Time fields that aren't provided default to 0.Thus, a date string
 like "3/30/2000" in "%mm/%dd/%yyyy" format results in a Date object for that
 date at midnight.formatStr is a free-form string that indicates special
 tokens via the % character.Here are some examples that will return a Date
 object:

 buildDate('3/30/2000','%mm/%dd/%y') // March 30, 2000
 buildDate('March 30, 2000','%Mon %d, %y') // Same as above.
 buildDate('Here is the date: 30-3-00','Here is the date: %dd-%m-%yy')

 If the format string does not match the string provided, an error message
 (i.e. String object) is returned.Thus, to see if buildDate succeeded, the
 caller can use the "typeof" command on the return value.For example,
 here's the dateCheck function, which returns true if a given date is
 valid,and false otherwise (and reports an error in the false case):

 function dateCheck(dateStr,formatStr) {
 var myObj=buildDate(dateStr,formatStr);
 if (typeof myObj=="object") {
 // We got a Date object, so good.
 return true;
 } else {
 // We got an error string.
