added:   wide characters can be used simultaneously with ascii characters
         now we have two kind of methods: one for ascii characters and the other for wide characters
         e.g.
           void UInt::ToString(std::string & result)
           void UInt::ToString(std::wstring & result)
         previous was only one:
           void UInt::ToString(tt_string & result)
         and the 'tt_string' was a typedef to either std::string or std::wstring
         and it was a little misleading to a user (he has to know what the tt_string is)
added:   file: ttmathmisc.h some useful functions
changed: classes: ExceptionInfo, ReferenceError and RuntimeError are used only with ascii characters
removed: macros: TTMATH_USE_WCHAR,  TTMATH_TEXT()
removed: typedefs: tt_char, tt_string, tt_ostringstream, tt_ostream, tt_istream

Version 0.9.0 prerelease (2009.09.11):
* added: support for wide characters (wchar_t)
wide characters are used when macro TTMATH_USE_WCHAR is defined
this macro is defined automatically when there is macro UNICODE or _UNICODE defined
some types have been changed
char -> tt_char
std::string -> tt_string
std::ostringstream -> tt_ostringstream
std::ostream -> tt_ostream
std::istream -> tt_istream
normally tt_char is equal char but when you are using wide characters then tt_char will be wchar_t (and so on)
(all typedef's are in ttmathtypes.h)
Version 0.9.0 prerelease (2009.09.13):
* fixed: Big::operator>>(std::istream&, Big<> &) didn't recognize values
in scientific mode (with 'e' character)
* added: support for wide characters (wchar_t, std::wstring)
* added: Big::IsInteger()
returns true if the value is integer (without fraction)
(NaN flag is not checked)
