Removed the J2KViewer module, which has been replaced by OPJViewer and fixed the error handling of j2k_decode in jp2.c, thanks to Robin Cornelius

-/** A class that eases the pain of running external
- *  processes from applications.
- *  Lets you run a program three ways:
- *  <OL>
- *     <LI><B>exec</B>: Execute the command, returning
- *         immediately even if the command is still
- *         running. This would be appropriate
- *         for printing a file.
- *     <LI><B>execWait</B>: Execute the command, but
- *         don't return until the command finishes.
- *         This would be appropriate for
- *         sequential commands where the first depends
- *         on the second having finished (e.g.
- *         <CODE>javac</CODE> followed by
- *         <CODE>java</CODE>).
- *     <LI><B>execPrint</B>: Execute the command and
- *         print the output. This would be appropriate
- *         for the UNIX command <CODE>ls</CODE>.
- *  </OL>
- *  Note that the PATH is not taken into account,
- *  so  you must specify the <B>full</B> pathname to
- *  the command, and shell builtin commands
- *  will not work. For instance, on Unix the above
- *  three examples might look like:
- *  <OL>
- *    <LI><PRE>Exec.exec("/usr/ucb/lpr Some-File");</PRE>
- *    <LI><PRE>
- *        Exec.execWait("/usr/local/bin/javac Foo.java");
- *        Exec.execWait("/usr/local/bin/java Foo");
- *        </PRE>
- *    <LI><PRE>Exec.execPrint("/usr/bin/ls -al");</PRE>
- *  </OL>
