Managed to get configuration settings collected from the user and put into the database.

The next steps are:

• load all configuration settings from database when the program starts and set up events to prompt the user based on configuration settings
• load configuration settings for user from database when a user changes their configuration settings and set up events to prompt user based on new configuration settings
• Interpret configuration settings into a more concrete schedule taking into account the timezone of the user
• Create prompts to send users about their feelings
