/**
	Procedural API Description

		The main aim is to make input validation expressible in a simple format.
		You define profiles which declare the required and optional fields and any constraints they might have.
		The results are provided as an object that makes it easy to handle missing and invalid input.

	Usage

		var results = dojo.validate.check(form, profile);

	Profile Object

		var profile = {
			// filters change the field value and are applied before validation.
			trim: ["tx1", "tx2"],
			uppercase: ["tx9"],
			lowercase: ["tx5", "tx6", "tx7"],
			ucfirst: ["tx10"],
			digit: ["tx11"],

			// required input fields that are blank will be reported missing.
			// required radio button groups and drop-down lists with no selection will be reported missing.
			// checkbox groups and selectboxes can be required to have more than one value selected.
			// List required fields by name and use this notation to require more than one value: {checkboxgroup: 2}, {selectboxname: 3}.
			required: ["tx7", "tx8", "pw1", "ta1", "rb1", "rb2", "cb3", "s1", {"doubledip":2}, {"tripledip":3}],

			// dependant/conditional fields are required if the target field is present and not blank.
			// At present only textbox, password, and textarea fields are supported.
			dependencies:	{
				cc_exp: "cc_no",	
				cc_type: "cc_no",	
			},

			// Fields can be validated using any boolean valued function.  
			// Use arrays to specify parameters in addition to the field value.
			constraints: {
				field_name1: myValidationFunction,
				field_name2: dojo.validate.isInteger,
				field_name3: [myValidationFunction, additional parameters],
				field_name4: [dojo.validate.isValidDate, "YYYY.MM.DD"],
				field_name5: [dojo.validate.isEmailAddress, false, true],
			},

			// Confirm is a sort of conditional validation.
			// It associates each field in its property list with another field whose value should be equal.
			// If the values are not equal, the field in the property list is reported as Invalid. Unless the target field is blank.
			confirm: {
				email_confirm: "email",	
				pw2: "pw1",	
			}
		};

	Results Object

		isSuccessful(): Returns true if there were no invalid or missing fields, else it returns false.
		hasMissing():  Returns true if the results contain any missing fields.
		getMissing():  Returns a list of required fields that have values missing.
		isMissing(field):  Returns true if the field is required and the value is missing.
		hasInvalid():  Returns true if the results contain fields with invalid data.
		getInvalid():  Returns a list of fields that have invalid values.
		isInvalid(field):  Returns true if the field has an invalid value.
