Water Front Proxy simulator

- This source includes the main App code of the LSTM and BiLSTM-based proxy models for determining waterfront location in an injection process.
The main program needs several sub-codes and functions for applying, so it can not be run independently. But the proxy models' structure and features can be reused from this source.
- The developed proxy models are trained with a mixture of numerical simulation data, common well data, and some pre-defined geometrical data. The trained models can be used for front location simulation independent from any numerical simulation data.
- Additional instructions for use are commented through the code's sections.
- Some examples of the training performance are attached too.
