/*---------------------------------- Check any form......

!!!!!!!!!!!----------------------------------------------------\/
in order to use this valedation you first have to enter 
the next data in each field you ant to validate:
validate="1" 
caption="ма иеб"  ---> the msg to show in the alert
regEx="(.*@{1}.*\..*)"  --> what content can this field get!
!!!!!!!!!!!----------------------------------------------------/\


Input ===> this.form (the form Object to be checked)
Output ==> Boolean result (true/false)

The form element should have these properties :
{
	validate --> either 1 or 0 (check or not).
	regEx --> the first regular expression.
	regEx2 --> the second regular expression.
		*(note)--> the check is regEx or regEx2 but not both.
	caption --> the text you want the user to get.
}

An example of a regular expression :
{
	(.*@{1}.*\..*) --> checks the email to be valid.
	(.{5,7}) --> any text at least 5 chars long but less then 7
	([0-9]) --> just the numeric values.
	(.*@{1}.*\..*) --> email
	regEx='([\W])' regEx2='([\w])'")' any text
	
	regEx=([0-9]{0,})
	regEx2=([a-zA-Z])
		result:
		{
			(the text box can be empty or has numbers but not letters)
				or
			(the text box can't be empty and contains only english letters)
		}
	Note: You don't have to put regEx, if none is present the field is checked to have something.
	Note: You can read all about Regular Expressions in the MSDN Library.
