Playing with the idea of tabular data

Much data in shell is tabular but current tools don't
treat it that way. I have added some tools to get the
feeling how things could be.

After setting up PATH and PYTHONPATH you can for example:

    ls.py * | select.py name,size | grep.py -c size '^0$'
    ls.py * | awk.py 'write(n=NR, name=c_name)'
