/*
The wxString typemaps below are sufficient to handle two cases but not
a third.
1) Arguments into wrapped C++ functions taking wxString as parameters can be
passed as python strings, not wxString. In fact you cannot create a wxString
from python, only in C++.
2) Wrapped C++ functions returning wxString will have that wxString
converted to a python unicode or string automatically.
Both of these features are a result of the wxString typemaps below. Note
that this philosophy is very agreeable, and is consistent with the
philosophy adopted by wxPython. In fact one might wish that KiCad did not
use wxString in any of its data structures, and merely used UTF8s, which
will convert automatically to and from wxString when needed.
There is another case that typemaps to not address, and no, this is not the
construction of wxString from python, but rather the examination of wxString
in situ, i.e. in a data structure within the BOARD. It does not match either
case above. So the class wxString {} spec block below is in here to allow
examination of a wxString's value when operating python interactively or
when printing a value in situ that was not returned from a wrapped function.
Remember wxString return values of functions are converted by the typemaps.
No wxString constructor is given to SWIG, since wxString contruction is
always done in C++, but python needs to know that it can delete a wxString
when necessary. And most importantly we need to see a string's contents so
the __str__() function must show content.
