Tasks done this week:

1) Followed the tutorials at http://www.openeering.com/scilab_tutorials, and created my own xcos module using the xcos skeleton.

2) Built scilab from source.

3) Studied bufferblock module available at http://forge.scilab.org/index.php/p/bufferblock/. I haven't been able to compile it, and am communicating with Yann - the developer of the module - for help.
