Need full_name() function

[DavidSagan]

Need a function that will return the "full" name string with isotope and charge state included. For example, full_name(Particle("He",2)) should return "He++".

It would be nice for full_name to have the option to return the unicode string with appropriate subscripts and superscripts. For example, return "³He" instead of "#3He"

I'm going to implement this with the existing ascii format, and then I'll figure out the unicode.

Note: full_name not yet exported.

It's exported now, still working on unicode implementation
