I added three java annotations to the reflect package: @AvroIgnore, @AvroName and @AvroMetadata.
Fields with the @AvroIgnore annotation will be treated as if they had a transient modifier, i.e. they will not be written to or rad from avro files.
Java fields with the @AvroName("alt_name") annotation will be renamed in the induced schema.
When reading an avro file into a new class via reflection, the reflection reader will also look for fields in the schema with the avro name.
For example, schema 'example' could be read into the class 'exampleClass'.
The @AvroMetadata(key="KEY", value="VALUE") annotation allows you to put an arbitrary key : value pair at every node in the schema.
I also extended the @Stringable annotation to java fields.
This way one can turn objects to strings where the annotation cannot be added to the class itself.
