Usage:	`php transpose_chords.php <range> [<hint>] ["strict"] ["font="<fontname>]`
Parameters:	`range` is a required integer, -11 to +11, and is the transposition in semitones `hint` optional, is the key of the tune, of the form [A-G]([#b])(m\|M\|min\|maj) `strict` optional keyword. Uses a stricter policy on what is a chord `font=<fontname>` optional, means only transpose chords displayed in font
Additional Help :	Invocation Instructions This is a pdf document
Comments:	eg php transpose_chords.php -4 C# font=StaffBold If range is 0, and no hint is given, convert all enharmonic spellings If range is not 0, and no hint is given, transpose according to "C" A "text chord" is a piece of text of the regular-expression form \s[A-G][#b]? (leading space, uppercase A-G, optional # or b) Trying to match the dim, dom, maj, aug, sus4, +9, add11, etc was considered fruitless but a keyword "strict" is available to try and limit what we call a chord \s[A-G][#b]? ?(M\|maj\|m\|min\|dim\|dom\|sus\|aug\|add\|7\|9\|11\|13\|b5\|b11\|b13)? (as above, but with optional trailing space followed by optional chord modifiers).
