Use Case: Registration

###Brief Description#

This use case describes how a user can register an account in the application.

###Basic Flow#

• The system requests that the user enter his/her name and password.
• The user enters his/her name and password.
• The system validates the entered name and password and creates an account for the user.

###Alternative Flows# #####Invalid Name / Password#
