first use current thread's classloader to load a class, if current thread does not have a classloader, use the class's current classloader to load a class.
This will make sure a class not packaged in parquet but on classpath loaded properly. Otherwise, for example, if you set your own ReadSupport class to the
Configuration object and expect it to be loaded by ParquetInputFormat, it will fail and throw ClassNotFoundException.
use utility method from Configuration class to load class to avoid ClassNotFoundException
Added ParquetWriter() that takes an instance of Hadoop's Configuration.
Fix to read a new avro schema...
Make setting requested projection and avro schema more independent, so that
you only need to set the Avro schema if it is different to the
writer's schema.
Support promotion of int, long and float to wider types.

This is specified in http://avro.apache.org/docs/current/spec.html#Schema+Resolution
Use a default Avro read schema when none specified in Parquet-Avro.
Add tests for reading Parquet files using the default
Avro schema.
Minor changes following Julien's review
