opencv-facial-recognition's Issues

Add an sqlite database to record the first face embedding

Instead of saving the face embedding to an in-memory list as we are currently doing (em_list, line 36) ,
save it to an sqlite database.
Create a seperate package (folder) within the project to house the repository functions and table definition.
What kind of table do we need?
The face embedding should be saved as a JSON in the text column.

What other columns do we want?

We want to be able to name the embedding (or the person it represents).
We want an internally generated id.
We want a timestamp.
