/*	prescription_validation.js - 2011 08 01 - Aaron Cooke
 *  -----------------------------------------------------
 *	This object handles most of the form validation and events for the prescription form
 *  in the prescription section of the checkout page. It's roughly organized as follows:
 *
 *		(Lines 1-80)		Comments
 *		(Lines 80-140)		Public Variables And Functions
 *		(Lines 140-360)		Private Variables And Potentially Re-Usable Functions
 *		(Lines 360-1060)	Private Functions For Validation Triggered By Continue onClick Event
 *		(Lines 1060-1400)	Private Functions For Validation Triggered By Sph And Cyl Control OnClick Or OnKeyPress Events
 *		(Lines 1400-1650)	Private Functions For Validation Triggered By OnClick Event Of Specific Radio Buttons
 *		(Lines 1650-1690)	Private Functions For Validation Triggered By OnClick Or OnKeyPress Events Of Shipping State Control
 *
 *	Generally speaking, functions in this object appear in the order in which they're called.
 *
 *  initialize()
 *  ------------
 *  Call this before attempting to use this class. Bad things will happen if you don't.
 *
 *  validateSphAndCyl()
 *  -------------------
 *  This function is called whenever the rx/sph or cyl controls in the new
 *  prescription form experience the onlick or onkeyup events. It takes the values from all four
 *  controls and runs them through a series of functions (starting at around line 1000) that compares
 *  these values against an algorithm constructed from the data in the spreadsheet provided
 *  by Warby Parker. This sequence of functions is also called once during form validation after the Continue
 *  button is clicked.
 *
 *  validateWhetherStateRequiresVerification()
 *  ------------------------------------------
 *  This function is called whenever a value is selected in the shipping-state select control. If
 *  the selected state requires prescription verification, the prescription-verification-method UL
 *  will appear. Otherwise, it will be hidden. The internal functions corresponding to this
 *  validation can be found at the end of this file.
 *
 *  handlePrescriptionControlClicked()
 *  ----------------------------------
 *  This function is called whenever one of the important radio buttons in the prescription checkout
 *  are clicked. This sequence of functions causes the corresponding display element and its
 *	children to become visible. It hides all display elements associated with sibling radio elements
 *  and any child display elements of those siblings. It also resets value of the children of the sibling
 *  display elements, clears any instances of the has-error style class and clears and hides the
 *  validation-problem element. The display element hierarchy is as follows:
 *
 *  prescription-glasses-control
 *		saved-prescription-control
 *  		saved-prescription-list
 *  	new-prescription-list
 *  		new-prescription-table
 *  		prescription-verification-method
 *		dont-have-control
 *  		dont-have-list
 *		call-doctor-control
 *  		call-doctor-list
 *  	need-bifocals-control
 *  		need-bifocals-div
 *  reading-glasses-control
 *		reading-glasses-list
 *  non-prescription-glasses-control
 *		non-prescription-glasses-list
 *
 *	validateControls()
 *	------------------
 *	This function is called whenever the OnClick even of the Continue button is triggered. The sequence of
 *	functions it triggers follows the hierarchy shown above such that only the necessary validations are
 *  performed. Any failed validation causes the {this.isValid} property to be set to {false}. Failed validations also
 *	set the corresponding property in the {currentValidationResult} object to be set to {true}. Once validation is
 *  complete, the state of the form controls, the contents of the validation-problem display element and the
 *	display state of this element are updated accordingly.
