    14 * Description: 

    15 * Declare TASN1EncBase128DER class.

    16 * Declare TASN1EncBase128DER class.  This encodes a given integer base 128,

    17 * most significant digits first, with the top bit set 1 on every

    18 * octet except the last.

    19 * The DER encoding of numbers in base 128 is common both the the encoding

    20 * of the tag number in high-tag-number form, and to the DER encoding of OID terms,

    21 * hence this class to encapsulate this commonality.
