Subject: [PATCH] ValueFilter's keys with the special field '*' will match all
 values and filter them out (true) or show (false). Sample: ``` valueFilter: {
   field1: {     '*': true, // filter out all values     'value1': true, //
 filter out value1     'value2': false // select to display value2   },  
 field2: {     '*': false, // select to display all values     'value1': true,
 // filter out value1     'value2': false // select to display value2   } }
 ```
