User My Profile: Edit

[erin-king]

As a logged in user
When I visit the profile page
I see a link to edit my profile
When I click "Edit Profile"
I am redirected to edit my profile form
Where I see my information auto populated and
I can change any or all the fields
When I fill in valid information
And I click on the submit button
I am redirected to my profile
Where I see a message saying my information has changed.
