Version 0.4.0 of FlowDesigner

Release Notes: The VFLOW_PATH environment variable is no longer required (it's determined from the --prefix configure option) if you don't add your own nodes. The FFTW library is no longer required to build Overflow. If you don't have it, the build will continue without FFT support. It's now possible to have Feedback loops in a flow. This is done by using the "Feedback" node and a demo is available in the examples directory. Overflow also supports throwing and catching exceptions within the flow using the "Throw" and "Catch" node. This is still undocumented. Support for AMD 3D Now! instructions in vector primitives. Rewrite of the Neural network toolbox to make it faster. There is more stuff in the "example" directory. There is updated html documentation. The layout of the links on the GUI (links can be broken lines) is improved. There are many new nodes.

Release Notes: This release includes new URL streams that can be specified by users at run time by using tcp:host:port, file:filename, etc. There is an automatic type conversion when using RCPtr = ObjectRef. Parameters passing at run-time from document parameters was fixed. This version now works with MARIE, fixes the String serialization, adds Vector conversion with toInt and toFloat nodes, and removes ownership on sockets, which caused exceptions on some systems. The Octave plugin now parses Octave file and executes properly, and a lot of operators on basic types were added, including add, sub, mul, div, and concat.
