Re: [myhdl-list] MEP 107 Initial support

I have merged this in now on bitbucket. Development is now on branch 0.9-dev, bug fixes for 0.8 on branch default. The merged-in new functionality is major - I encourage all to test further. If it all works as advertised, this is exciting because it is a fantastic example of how we can support advanced features (interfaces) in conversion even when the target languages don't support them. Let's test this thoroughly, and then create a lot of buzz about it :-) NOTE: There are 2 known issues to be resolved, one with list of Signals naming (discovered by jck), another with dynamically set attributes (discovered by me, see failing unit test in conversion/toVerilog and conversion/toVHDL. I also propose that MEP 107 is adapted to the current implementation if necessary - (iff there are features not yet supported I suggest to factor them out for a future MEP). Thanks Chris for already starting with the documentation.
