[Mohammad Akhlaghi]

branch: master
commit 647406fff3c82a1e5f941e205a28f9cc36dbb2f2
Author: Mohammad Akhlaghi <address@hidden>
Commit: Mohammad Akhlaghi <address@hidden>

    Table utility bare minimum structure in place
    
    Following the TEMPLATE bare minimum structure, the new `Table' utility's
    structure is now in place along with a simple `--information' option which
    will later print the table information.
