ANN: Lush 2.0 beta release

Folks, a first Lush 2.0 beta release is out.
Download: https://sourceforge.net/projects/lush/files

Many changes have been made since the last Lush 1.x release
that will facilitate future development. But there are also
a number of visible changes and Lush 2.0 is not fully backward
compatible. The differences include:
- Lush 2.x is case-sensitive
- outdated packages have been dropped (HTK, Torch, and others)
- many functions have been renamed (see namespace lush1-)

Some things are currently broken, including
- the make-standalone facility
- some outdated packages (video4linux, sn28, and others)
- support for complex numbers

New features include
- builtin math functions work on arrays
- a namespace facility
- a small datatype library (heap, sets, graph)
- a gnuplot interface

Have fun,
Ralf
