NAME

       Alzabo::Create::ColumnDefinition - Column definition object for schema creation

SYNOPSIS

	 use Alzabo::Create::ColumnDefinition;

DESCRIPTION

       This object holds information on a column that might need to be shared with another column.  The reason this class exists is that if a col-
       umn is a key in two or more tables, then some of the information related to that column should change automatically in multiple places
       whenever it changes at all.  Right now this is only type ('VARCHAR', 'NUMBER', etc) and length/precision information.  This object also has
       an 'owner', which is the column which created it.
