Short Description :

This function checks for a valid date.
The  input is the form object for which date 
validation is required.

This function will call either isDateDMY or isDateMDY
based on the second parameter. If 'DMY' is passed in the second 
parameter, Date will be validated for "DD/MM/CCYY" format.
If 'MDY' is passed in the second parameter, Date will be validated
for "MM/DD/CCYY" format. 

If Nothing is passed, "MM/DD/CCYY" format is assumed.

Date between 1900A.D and 9999 A.D will be accepted.

Input Parameters : Date, Format 

Format : Two formats are currently available
1. MM/DD/CCYY
2. DD/MM/CCYY
Default : MM/DD/CCYY

Return Value : This returns false in case of an 
invalid date.
