// This bit is important.  It detects/adds XMLHttpRequest.sendAsBinary.  Without this
// you cannot send image data as part of a multipart/form-data encoded request from
// Javascript.  This implementation depends on Uint8Array, so if the browser doesn't
// support either XMLHttpRequest.sendAsBinary or Uint8Array, then you will need to
// find yet another way to implement this. (This is left as an exercise for the reader,
// but if you do it, please let me know and I'll integrate it.)

# 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.
