JSONDB implementation
View gist:1039559
###
# JSONDB - a compressed JSON format
# By Devon Govett
# Originally proposed by Peter Michaux - http://michaux.ca/articles/json-db-a-compressed-json-format
#
# jsondb.pack converts an array of objects with the same keys (i.e. from a database)
# and flattens them into a single array, which is much smaller than the pure json
# representation where the keys are repeated for each item in the array.
# Combine with JSON.stringify to send compressed JSON data over the network.
