Make runnable test example

[realamirhe]

Describe the bug
Running Mnist on the latest version of pymonntorch and CoNex can not run the mnist example.

To Reproduce
Seems that synapse.tensor has been replace with matrix but there need moderation on the hole project.

Steps to reproduce the behavior:

Traceback (most recent call last):

    net.initialize()

This is not a bug. upgrade Pymonntorch to the last version.

[realamirhe]

I guess the issue happened because the latest released version available via pip is 0.1.1

$ pip index versions pymonntorch

pymonntorch (0.1.1)
Available versions: 0.1.1, 0.1.0
  INSTALLED: 0.1.1
  LATEST:    0.1.1

But the latest version released version in GitHub is 0.1.2 latest
