use(PythonContext) -- install variables from a python context

Description

This method makes all the variables in a PythonContext available outside the context.

i1 : ctx = new PythonContext

o1 = ctx

o1 : PythonContext
 
i2 : ctx "f = lambda x:x**2"
 
i3 : ctx "x = 5"
 
i4 : ctx "y = f(x)"
 
i5 : f

o5 = f

o5 : Symbol
 
i6 : x

o6 = x

o6 : Symbol
 
i7 : y

o7 = y

o7 : Symbol
 
i8 : use ctx
 
i9 : f

o9 = <function <lambda> at 0x710294d22a30>

o9 : PythonObject of class function
 
i10 : x

o10 = 5

o10 : PythonObject of class int
 
i11 : y

o11 = 25

o11 : PythonObject of class int
