+ * This ViewHelper explodes a string by a specified glue and limits the output to a specified number of elements.
+ * It is useful for formatting settings or any other string that needs to be split and limited.
+ * Example usage:
+ *
+ * <code>
+ * {namespace e2=JWeiland\Events2\ViewHelpers}
+ * <e2:cropString content="{contentSeperatedByCommas}" glue="," limit="5" />
+ * </code>
+ *
+ * In this example, the `cropString` ViewHelper will take the `contentSeperatedByCommas` string, split it by commas,
+ * and return the first 5 elements as a comma-separated string. If there are more than 5 elements,
+ * it will append "..." to the end of the string.
