Subject: [PATCH] version bump 0.7.0: more intelligent tokenizer

- Literal characters between numbers (fixes #7, h/t @sysarchitect)
- .0/.00/.000 recognized as potential date tokens
- s+.0+ generates two tokens (with proper handling for `hh .00 .000`)
- proper handling of format strings with mixed 0 and #

 The magic in the next line is to ensure that the negative number is passed as
 positive when there is an explicit hyphen before it (e.g. `#,##0.0;-#,##0.0`):
 
 ```
-        out[i].v = write_num(out[i].t, out[i].v, (flen >1 && v < 0 && i>0 && out[i-1].v == "-" ? -v:v));
-        out[i].t = 't';
-        i = jj-1; break;
-      case 'G': out[i].t = 't'; out[i].v = general_fmt(v,opts); break;
-```

-The default case should not be reachable.  In testing, add the line
-`default: console.error(out); throw "unrecognized type " + out[i].t;`

   }
