+/**
+ * CountingString example
+ * by Daniel Shiffman.  
+ * 
+ * This example demonstrates how to use a IntDict to store 
+ * a number associated with a String.  Java HashMaps can also
+ * be used for this, however, this example uses the IntDict
+ * class offered by Processing's data package for simplicity
+ * and added functionality. 
+ *
+ * This example uses the IntDict to perform a simple concordance
+ * http://en.wikipedia.org/wiki/Concordance_(publishing)
