Please note that, any one of these member variables can be null,
and any accesses to them should be prepared to handle such a case.
Also, it is implied that phoneNumber is more often populated than
name is, (think of calls being dialed/received using numbers where
names are not known to the device), so phoneNumber should serve as
a dependable fallback when name is unavailable.
One other detail here is that this CallerInfo object reflects
information found on a connection, it is an OUTPUT that serves
mainly to display information to the user.  In no way is this object
used as input to make a connection, so we can choose to display
whatever human-readable text makes sense to the user for a
connection.  This is especially relevant for the phone number field,
since it is the one field that is most likely exposed to the user.
As an example:
  1. User dials "911"
  2. Device recognizes that this is an emergency number
  3. We use the "Emergency Number" string instead of "911" in the
    phoneNumber field.
What we're really doing here is treating phoneNumber as an essential
field here, NOT name.  We're NOT always guaranteed to have a name
for a connection, but the number should be displayable.

Returns the column index to use to find the "person_id" field in
the specified cursor, based on the contact URI that was originally
queried.
This is a helper function for the getCallerInfo() method that takes
a Cursor.  Looking up the person_id is nontrivial (compared to all
the other CallerInfo fields) since the column we need to use
depends on what query we originally ran.
Watch out: be sure to not do any database access in this method, since
it's run from the UI thread (see comments below for more info.)

Returns:the columnIndex to use (with cursor.getLong()) to get the
person_id, or -1 if we couldn't figure out what colum to use.
TODO: Add a unittest for this method.  (This is a little tricky to
test, since we'll need a live contacts database to test against,
preloaded with at least some phone numbers and SIP addresses.  And
we'll probably have to hardcode the column indexes we expect, so
the test might break whenever the contacts schema changes.  But we
can at least make sure we handle all the URI patterns we claim to,
and that the mime types match what we expect...)
