+/**
+ * Set型のPropertyEditorクラス。<p>
+ * カンマ区切りの文字列をjava.util.Set型のオブジェクトに変換する。カンマをセパレータではない文字列として指定したい場合は、"￥"でエスケープする。<br>
+ * 最初と最後の空白と改行前後の空白はトリムされる。
+ * 空白は、{@link java.lang.Character#isWhitespace(char)}で判定される。
+ * 但し、空白を文字列の前後に付加したい場合には、"で囲むとトリムされない。"を文字列の両端に意図的に付加したい場合には、"を二重に重ねて記述する。<br>
+ * "&lt;!--"と"--&gt;"に囲まれた文字列はコメントと解釈され無視される。<br>
+ * "${"と"}"に囲まれた文字列は、同名のシステムプロパティと置換される。<br>
+ * "${\t}"、"${\n}"、"${\r}"、"${\f}"は、エスケープシーケンスとして置換される。<br>
+ * "￥u"から始まる６文字は、ユニコード文字列として置換される。<br>
+ * <p>
+ * 例：<br>
+ * &nbsp;&nbsp;A,B, C  <br>
+ * &nbsp;&nbsp;C, D,E ,&lt;!--F,<br>
+ * &nbsp;&nbsp;G,--&gt;"H ",""I""<br>
+ * <br>
+ * &nbsp;のような文字列が<br>
+ * <br>
+ * &nbsp;&nbsp;Set set = new LinkedHashSet();<br>
+ * &nbsp;&nbsp;set.add("A");<br>
+ * &nbsp;&nbsp;set.add("B");<br>
+ * &nbsp;&nbsp;set.add(" CC");<br>
+ * &nbsp;&nbsp;set.add(" D");<br>
+ * &nbsp;&nbsp;set.add("E ");<br>
+ * &nbsp;&nbsp;set.add("H ");<br>
+ * &nbsp;&nbsp;set.add("\"I\"");<br>
+ * <br>
+ * &nbsp;のように変換される。<br>
