A JSON parsing and encoding library optimized for ease of use and high

To get started, see the documentation for the 'Data.Aeson' module below.

Parsing performance on an early 2011 MacBook Pro (2.2GHz Core i7), running
64-bit GHC 7.6.3, for mostly-English tweets from Twitter's JSON search API:

* 0.8 KB: 34124 msg/sec (27.8 MB/sec)

* 6.4 KB: 6833 msg/sec (43.0 MB/sec)

* 11.8 KB: 3410 msg/sec (39.2 MB/sec)

* 31.2 KB: 1157 msg/sec (35.3 MB/sec)

* 61.5 KB: 542 msg/sec (32.5 MB/sec)

Handling heavily-escaped text is a little more work. Here is parsing
performance with Japanese tweets, where much of the text is entirely

* 14.6 KB: 2101 msg/sec (30.0 MB/sec)

* 44.1 KB: 667 msg/sec (28.7 MB/sec)

* 82.9 KB: 360 msg/sec (29.2 MB/sec)

Encoding performance on the same machine and data:

* English, 0.8 KB: 109697 msg/sec (89.3 MB/sec)

* English, 6.4 KB: 18517 msg/sec (116.4 MB/sec)

* Engish, 61.5 KB: 1963 msg/sec (118.0 MB/sec)

* Japanese, 14.6 KB: 12140 msg/sec (173.5 MB/sec)

* Japanese, 44.1 KB: 3980 msg/sec (171.3 MB/sec)

(A note on naming: in Greek mythology, Aeson was the father of Jason.).
