	Format:
		Validate(Field,Type of validation,Alert Label, Mandatory, LengthCheck, LengthAlert)
		1. Field - The field that must be validated. e.g.: document.Form.FieldName
		2. Types - Refer below.
		3. Alert Label - The text that will throw up in the alert.
			Default label is available for type no.6, 7, 9
		4. Mandatory - Some value must be given if a field is mandatory(Refer Step 3).
		5. LengthCheck - Maximum and minumum length of field seperated by ,.
			e.g.: "5,15"
			a. If minimum is not necessary then "0,10"
			b. If maximum is not necessary then "10,0"
		6. LengthAlert - The alert that should pop up when the above condition fails.
		
	Types:
		1. empty.
		2. alphanumeric.
			Allows: a-z,A-Z,0-9
		3. alphabets.
			Allows: a-z,A-Z
		4. numbers.
			Allows: 0-9
		5. float.
			Allows: 0-9,.
		6. mobile/phone.
			Allows: 0-9,-,spaces
		7. email.
		8. locations.
			Allows: a-z,A-Z,0-9,-,_,.,spaces
		8. image.
			Allows: jpg,jpeg,gif
		10. html.
			Allows: html, htm formats.
		11. other format.
			Definition: other format - .FormatType (e.g: other format - csv)
			The above is for checking for other formats. Multiple formats must be seperated
			with a '|' (e.g: other format - csv|exe).
		12. Any other arguement:
			e.g: a-z,0-9,_,spaces,comma,-
				
	Steps in validation:
		1. Check validation type.
		2. Check whether field is mandatory.
		3. Mandatory will be undefined or "" if it is omitted while calling the function.
		4. Check if there is any value in the field.
		5. If there is value then validate.
		6. Check if there is any length validation.
