Add the legacy database model

I added the legacy database model into the app.

In order to do that I:

- created the urls.py and views.py file (required by Django)
- created the legacy model using the inspectdb tools given by Django and
stored in models.py
- followed the process to initialize the migrations at the stage of the
model (resulting in the creation of the migrations folder)

+# This is an auto-generated Django model module.
+# You'll have to do the following manually to clean this up:
+#   * Rearrange models' order
+#   * Make sure each model has one field with primary_key=True
+#   * Make sure each ForeignKey has `on_delete` set to the desired behavior.
+#   * Remove `managed = False` lines if you wish to allow Django to create, modify, and delete the table
+# Feel free to rename the models, but don't rename db_table values or field names.
