-------------------------------------------------------------
r908235 commits the Printable interface and implements it in ClusterBase,
DirichletCluster and Model. It does not modify ClusterDumper so current dump
formats are unchanged, but that is the remaining task to complete this issue.
Here is what was done versus the above requirements:
1. We need an efficient, binary encoding for serialization and deserialization:
No changes to Writable utilization
2. We need a Json encoding encoding for serialization and deserialization:
asJsonString in Printable interface supports this
3. We need a complete, human-readable encoding for output only: recommend using
asJsonString if completeness is needed
4. We need a human-readable encoding for output only: asFormatString(bindings)
implements simplified, more readable notations with optional bindings
5. We need a human-readable toString() encoding for debugging only: toString
generally calls asFormatString(null)
