added comment
added automatic conversion from FileObj to FILE*, fflush(sout) now works (getc(sout) does not necessarily work, because getc can be a macro)
added arraysize
split r_status.h
split r_fileobj.h
added d.cc for dumping
removed TODO
relaced fdump by wrdump
made FileObj implement Writable; implemented <<dump to string
added inelegant implementation of Formatter, no automatic conversion
added first working Formatter template
moved Formatter::format to a static member function
added DEFINE_FORMATTER; moved format implementation outside the class
moved Formatter to separate file
implemented Dumper (stdout << dump(...)) using Formatter
split out operator<< on Formatter
added dumping with a prefix
added dump with more args; made dump buffer its output
added r_stringwritable.h
split wrdump, dump etc. to r_dump.h
