Test PyMathics module

This is a Python module for Mathics that is an simple "Hello, World" example that is typically used as a minimal example for demonstration.

Here we are demonstrating how to write a PyMathics module.

To install in development mode (run code from the source tree):

$ make develop

After installing inside Mathics you can load this using the LoadModule[] function.

Then to the function Pymathics\`Hello[] and the variable PyMathics\`$HelloUser will be available.

$ mathicsscript
In[1]:= LoadModule["pymathics.hello"]
Out[1]= pymathics.hello

In[2]:= PyMathics`Hello["World"]
Out[2]:= Hello, World!

In[3]:= PyMathics`$HelloUser
Out[3]:= $your-login-name$
