      public Asn1Object(int tag, int length, byte[] value)
      Construct a ASN.1 TLV. The TLV could be either a constructed or primitive entity.

      The first byte in DER encoding is made of following fields, 

      -------------------------------------------------
|Bit 8|Bit 7|Bit 6|Bit 5|Bit 4|Bit 3|Bit 2|Bit 1|
-------------------------------------------------
|  Class    | CF  |     +      Type             |
-------------------------------------------------
      • Class: Universal, Application, Context or Private
      • CF: Constructed flag. If 1, the field is constructed.
      • Type: This is actually called tag in ASN.1. It indicates data type (Integer, String) or a construct (sequence, choice, set).
