Creating example of LNNs with Traditional NN

[anas-rz]

Hi, We had a discussion with the IBM Neuro-Symbolic AI Team regarding contributing to LNN. One particular application type I became interested in is using them with traditional NN-based approaches. I suggest LNN repository should have some examples with public datasets like keras and Theseus. These examples help practitioners get a head-first experience of the framework. I look forward to contributing such one-click examples. Thanks.
