toExternalString(PythonObject) -- unambiguous string representation of a python object

Description

This returns a string beginning with pythonValue and that uses Python's builtin repr function to obtain a string that potentially may be evaluated using value(String) to return a Python object equal to x.

i1 : hello = toPython "Hello, world!"

o1 = Hello, world!

o1 : PythonObject of class str
 
i2 : toExternalString hello

o2 = pythonValue "'Hello, world!'"
 
i3 : value oo

o3 = Hello, world!

o3 : PythonObject of class str

Note that describe does essentially the same thing, but returns a Describe object.

i4 : describe hello

o4 = pythonValue 'Hello, world!'
