Used to accumulate values by category. It might be useful
for example in a billing program to accumulate hours by
various categories.
It could be used to count how many times various words
occurred in a document.
All you need is:
   buckets.accumulate( "somecategory", someamount );
And Accumulate looks after creating the buckets to
accumulate new categories for you.
e.g.
Accumulate buckets = new Accumulate( 20 );
buckets.accumulate( "ugli fruit", 3 );
buckets.accumulate( "peaches", 10 );
buckets.accumulate( "strawberries", 15 );
buckets.accumulate( "peaches", 14 );
String[] categories = buckets.categories();
// prints:
// peaches:24
// strawberries:15
// ugli fruit:3
for ( int i=0; i<categories.length; i++ )
   {
   System.out.println( categories[i]
   + ":"
   + buckets.total( categories[i] ));
   }
You can test the app with
java.exe -jar accumulate.jar
The bucket icon represents one of the buckets used to accumulate totals.
It is not useful as a standalone program, just as code you can add to your own programs.
