brought documentation up to date with goals

metaworker fault tolerance: failed work is placed back on the work list to be re-attempted

documentation adjustment

Implemented worker pipelining. During computation the number of workers is always held at maximum

randomize turned on for fractal demo, support for block filler example in sample server

Fixed randomize

Added randomize option which randomizes the work before partitioning

Added cluster support. Work can now be send out to a cluster of metaworker servers. Added a port option for metaworker servers.

Introduced AJAXWorker(), a worker type that can offload work to a server-side process, and metaworker_server, a nodejs-based metaworker server.

Modified DFT example to include mapper globals for signal and N

Merge branch 'master' of git://github.com/Maciek416/metaworker

Added "globals" parameter option to metaworker (see fractal example for usage)

Added canvas to draw the computed DFT spectrum.

Updated and fixed bugs in DFT example
