 * Class GF_Field
 *
 * This class provides the base functionality for developers when creating new fields for Gravity Forms. It facilitates the following:
 *  Adding a button for the field to the form editor
 *  Defining the field title to be used in the form editor
 *  Defining which settings should be present when editing the field
 *  Registering the field as compatible with conditional logic
 *  Outputting field scripts to the form editor and front-end
 *  Defining the field appearance on the front-end, in the form editor and on the entry detail page
 *  Validating the field during submission
 *  Saving the entry value
 *  Defining how the entry value is displayed when merge tags are processed, on the entries list and entry detail pages
 *  Defining how the entry value should be formatted when used in csv exports and by framework based add-ons
