Lightweight string buffer class (for ISO-8859-1 text)
A string object is mainly used to create trace text. Text is easily appended using printf-style format strings and variable argument lists. Memory can be allocated in blocks (aligning) to reduce overhead when appending multiple small strings. It is comparable against POSIX extended regular expressions. By creating traces in string buffers it is easy to direct library output to any kind of stream (console, file, serial, network, plugin, device e.t.c). Apart from traces a string can be used for generic dynamic text manipulation. If the library is compiled with plugin support (CSDBG_WITH_PLUGIN) or with support for stack trace syntax highlighting (CSDBG_WITH_HIGHLIGHT) a string object gets equipped with a method to tokenize it using POSIX extended regular expressions and other advanced text processing methods. This class is not thread safe, the caller must implement thread sychronization
