Wrapper around terminal styling, screen positioning, and keyboard input

Blessed is a thin, practical wrapper around terminal capabilities in Python. Brief Overview -------------- *Blessed* is a more simplified wrapper around curses, providing : * Styles, color, and maybe a little positioning without necessarily clearing the whole screen first. * Works great with standard Python string formatting. * Provides up-to-the-moment terminal height and width, so you can respond to terminal size changes. * Avoids making a mess if the output gets piped to a non-terminal: outputs to any file-like object such as *StringIO*, files, or pipes. * Uses the `terminfo(5)`_ database so it works with any terminal type and supports any terminal capability: No more C-like calls to tigetstr_ and tparm_. * Keeps a minimum of internal state, so you can feel free to mix and match with calls to curses or whatever other terminal libraries you like. * Provides plenty of context managers to safely express terminal modes, automatically restoring the terminal to a safe state on exit. * Act intelligently when somebody redirects your output to a file, omitting all of the terminal sequences such as styling, colors, or positioning. * Dead-simple keyboard handling: safely decoding unicode input in your system's preferred locale and supports application/arrow keys. * Allows the printable length of strings containing sequences to be determined. Blessed **does not** provide... * Windows command prompt support. A PDCurses_ build of python for windows provides only partial support at this time -- there are plans to merge with the ansi module in concert with colorama to resolve this.
