* GravityRanger // Gravity Forms Reset Button
* https://gravityranger.com/gravity-forms-reset-button/
*
* Use this code snippet to add a reset button to your forms.
* Code snippet will add the button to all forms by default.
*
* Instructions:
*
*  1. Copy and paste the snippet into your themes functions.php file or use a functionality plugin like WPCodeBox
*  2. Add your form ID to the filter if you only want to add the button to one form (i.e gform_submit_button_ID)
*  3. Option: You can change the value (line31) to whatever you'd like (value="Button Text")
*
* Known Limitations:
*
*  1. It does not work on all pages in a multi-page forms
*  2. It will not clear fields populated dynamically
*  3. It will not clear a Product field that uses the Calculation field type
