       o      IBase64Stream<CryptType>(std::istream&in,size_tbufSize=1000):
              This  constructor  initializes  a std::istream providing it with an FBB::IBase64Buf stream buffer.
              The IBase64Buf’s constructor receives all arguments that are passed to this constructor.

              - IBase64Stream<ENCRYPT> objects perform base64 encoding;
              - IBase64Stream<DECRYPT> objects perform base64 decoding;
              - IBase64Stream<CryptType> objects obtain the bytes to encode or decode from std::istream&in;
              - The internally used IFilterBuf is initialized with a buffer of size bufSize, using a lower bound
              of 100.

              The constructor uses a configurable buffer size for reading. Characters that were  read  into  the
              buffer  but  are  not  part of the actual base64 encoded data are unavailable after completing the
              base64 decrypting. If information beyond the base64 input  block  should  remain  available,  then
              specify a buffer size of 1.

       Copy and move constructors (and assignment operators) are not available.

FBB::IBase64Stream  objects  may  be  used to base64 encode or decrypt information that is available on a
       separate std::istream.

       The classIBase64Stream is a class template, using a FBB::CryptType template non-type parameter.  Objects
       of  the class FBB::IBase64Stream<FBB::ENCRYPT> base64 encode the information they receive, objects of the
       class FBB::IBase64Stream<FBB::DECRYPT> base64 decode the information they receive.

       #include <iostream>

       #include <bobcat/ibase64stream>

       using namespace std;
       using namespace FBB;

       int main()
       {
           IBase64Stream<ENCRYPT> in(cin);
       }

bobcat/ibase64stream - defines the class interface

       Since the class uses public derivation from std::istream, all members of this class can be used.
