This is like print but print into a given buffer. If the resulting
string will not fit into \c buffer then a new buffer is allocated and
returned, otherwise \c buffer is returned. the caller must delete[]
the returned memory if is not \c buffer.
\c prefix and \c suffix must be >= 0. Exactly \c prefix characters and
at least \c suffix characters are available in the buffer before
and after the printed string, respectively. \c bufferLength is the
length of buffer and should not be adjusted by the caller to
account for \c prefix or \c suffix.
