 It's pretty hard to add a new type of profile field to BuddyPress; some
 plugins such as [https://github.com/donmik/buddypress-xprofile-custom-
 fields-type/](this one) do a good job, but we make it hard because we
 hardcoded values and checks and templates across several places. Examples
 of new profile field types might be inspired by HTML5 input types such as
 number or email (#4694), or a birthday field (#4582), or advanced types
 like a map/co-ord mashup (#5028).

 Places that need changing (currently via actions or filters) when you add
 a new profile field type are listed below. There may be more, as I'm still
 re-discovering where everything is:

 * Templates in `/members/single/profile/edit.php`,
 `/members/register.php`, `BP_XProfile_Field->render_admin_form()`.
 * Logic in `bp_core_screen_signup()`, `xprofile_screen_edit_profile()` and
 `xprofile_set_field_data()`.

 I believe profile types should be implemented as a class; there's a lot of
 places where we can benefit from an object orientated approach to profile
 field types. And, eventually, I'd like it to be as easy to add a profile
 field type to BuddyPress as creating a Group extension is. No changes to
 other files, filters, or actions should be required.
