-### A ASN1 parser with easy and simple API
-
-```
-// encoding
-Asn1Integer aValue = new Asn1Integer(8899);
-byte[] encoded = aValue.encode();
-
-// decoding
-byte[] contentToDecode = ...
-Asn1Integer decodedValue = new Asn1Integer();
-decodedValue.decode(contentToDecode);
-Integer value = decodedValue.getValue();
-```
-
-### Data-driven ASN1 encoding/decoding framework and parser
-
-With the following definition from Kerberos protocol
-```
- AuthorizationData ::= SEQUENCE OF SEQUENCE {
-     ad-type         [0] Int32,
-     ad-data         [1] OCTET STRING
- }
- ```
- 
-You can model AuthzDataEntry as follows
-```java
-public class AuthzDataEntry extends Asn1SequenceType {
-    static int AD_TYPE = 0;
-    static int AD_DATA = 1;
-
-    public AuthzDataEntry() {
-        super(new Asn1FieldInfo[] {
-                new Asn1FieldInfo(AD_TYPE, Asn1Integer.class),
-                new Asn1FieldInfo(AD_DATA, Asn1OctetString.class)
-        });
-    }
-
-    public int getAuthzType() {
-        Integer value = getFieldAsInteger(AD_TYPE);
-        return value;
-    }
-
-    public byte[] getAuthzData() {
-        return getFieldAsOctetBytes(AD_DATA);
-    }
-}
-```
-
-And then define AuthorizationData simply
-```java
-public class AuthorizationData extends Asn1SequenceOf<AuthzDataEntry> {
-
-}
-```
-
-Then you can process with above definitions, encode and decode, without caring about the details.
-
-Think about how to implement the following more complex and pratical sample from [ITU-T Rec. X.680 ISO/IEC 8824-1](http://www.itu.int/ITU-T/studygroups/com17/languages/X.690-0207.pdf):
-```
-A.1 ASN.1 description of the record structure
-The structure of the hypothetical personnel record is formally described below using ASN.1 specified in
-ITU-T Rec. X.680 | ISO/IEC 8824-1 for defining types.
-
-PersonnelRecord ::= [APPLICATION 0] IMPLICIT SET {
-    Name Name,
-    title [0] VisibleString,
-    number EmployeeNumber,
-    dateOfHire [1] Date,
-    nameOfSpouse [2] Name,
-    children [3] IMPLICIT
-    SEQUENCE OF ChildInformation DEFAULT {} 
-}
-
-ChildInformation ::= SET {
-    name Name,
-    dateOfBirth [0] Date
-}
-
-Name ::= [APPLICATION 1] IMPLICIT SEQUENCE {
-    givenName VisibleString,
-    initial VisibleString,
-    familyName VisibleString
-}
-
-EmployeeNumber ::= [APPLICATION 2] IMPLICIT INTEGER
-Date ::= [APPLICATION 3] IMPLICIT VisibleString -- YYYYMMDD
-```
-Similarly as above, we can have (from the unit test codes):
-```java
-public class PersonnelRecord extends TaggingSet {
-    private static int NAME = 0;
-    private static int TITLE = 1;
-    private static int NUMBER = 2;
-    private static int DATEOFHIRE= 3;
-    private static int NAMEOFSPOUSE = 4;
-    private static int CHILDREN = 5;

-            new Asn1FieldInfo(NAME, -1, Name.class),
-            new Asn1FieldInfo(TITLE, 0, Asn1VisibleString.class),
-            new Asn1FieldInfo(NUMBER, -1, EmployeeNumber.class),
-            new Asn1FieldInfo(DATEOFHIRE, 1, Date.class),
-            new Asn1FieldInfo(NAMEOFSPOUSE, 2, Name.class),
-            new Asn1FieldInfo(CHILDREN, 3, Children.class, true)
-    };
