Function Description when you don´t define PutDescription

[jlaybar]

If you define a TOL function and don´t include a description for it using
PutDescription then TOL should write the code of the function instead of the
description.
The problem is that TOL gets confused when printing that code.

I forgot to mention that now we need to use variable DoUnparseNodes to activate
Unparse function in each node. We can see this better with an example:

With this code:
_

Real x = {

Real a = 1;
Text a = "Hola";
TRUE

};

We get the message:
_

ERROR: Variable 'a' already defined.

Note: You can see the sentence where Variable "a" has been created by setting
DoUnparseNodes global variable to 1
Variable "Text a" can not be created

But if we set DoUnparseNodes first:
_

Real (DoUnparseNodes:=1);
Real x = {

Real a = 1;
Text a = "Hola";
TRUE

};

The message is more verbose:
_

ERROR: Variable 'a' already defined as "Real a = 1"
Variable "Text a" can not be created
