Output Table Fields to a List in sap abap

When you're looking at the structure of a table, SAP will let you print the structure, but it
won't let you save the structure. This can be annoying. This report outputs the table structure
to a list. At this point the user can use the System->List->Save->Local file command to save
the list to a file.
