     *
     * 1) allocate space for each column. Comment out columns you don't

     * column data you want to store. Remeber, data will be stored in

     *

     *   Octet String: (2 * len) + 2 [2 ASCII chars per byte + "0x"]
     *   Integers    :  12 [ASCII len for smallest negative number]
     *
     * 2) You also need to allocate space for the row index. This will
     * be stored as an OID, which means that Octet Strings need to
     * be treated a little differently. Specifically, you will need
     * (4 * len) + 4 [3 ASCII chars per byte + 1 for ., + 4 for len].
     *
     * 3) Also, remeber to add space for the identifier and seperator
     * characters (for example, each column is prefixed by the
     * column number and a semicolon. To allow for the maximum
     * column values, 12 bytes [11 for oid + 1 for ':'] per
     * column are added).
