ResourceFieldSchema uses DataType for types; DataType is a collection of static 
methods and lookups, and cannot define a type. Instead, currently byte values 
are currently used to represent types, and set of byte constants for the 
various types lives in DataType. So ResourceFieldSchema should have types be 

Also, as I am working through a toy implementation, I find that it's very 
useful to have both ResourceSchema and ResourceStatistics declare getters and 
setters -- this lets various serialization libraries serialize/deserialize them
