/**
* Clears the selected form elements. Takes the following actions on the matched elements:
* - input text fields will have their 'value' property set to the empty string
* - select elements will have their 'selectedIndex' property set to -l. Normann change it from -1 to '',
* since set to -1, actually is not clearing the field, it change its value to null, and when submit the form the field belonged to,
* the field value will be treated to a pure string "null", and this is not what it suppose to do.
* - checkbox and radio inputs will have their 'checked' property set to false
* - inputs of type submit, button, reset, and hidden will *not* be effected
* - button elements will *not* be effected
*
* @example $('.myInputs').clearFields();
* @desc Clears all inputs with class myInputs
*
* @name clearFields
* @type jQuery
* @cat Plugins/Form
