Description

Now that the specification with respect to page level checksums has been clarified (see https://jira.apache.org/jira/browse/PARQUET-1539), we can actually implement it. What needs to be done:

• Implement calculating and writing checksums on write path
• Implement checksum validation on read path
• Make writing out checksums and validation on reads optional (default off)
• Implement tests
