/**
 * FieldMapWrapper is used in combination with PageField and StructuredContentField classes.
 * It is used by the DisplayContentTag to allow for simpler use of these
 * entities within JSP pages.
 *
 * For example, instead of ${page.pageFields.body.value}, this class allows the JSP
 * syntax to be ${page.body} supporting more readable JSP code.
