Comment (by r-a-y):

 `02.patch` switches the syntax to use the same recursive, nested query
 syntax as introduced by boonebgorges to WP and to `BP_XProfile_Query`.
 (See comment:7.)

 I've also opted to use the approach by boonebgorges to separate the
 recursive query syntax into its own class - `BP_Recursive_Query` - though
 this is not in WP core.  (See
 https://core.trac.wordpress.org/ticket/29642#comment:6 for more details.)
 `BP_Activity_Query` extends this class; at the moment, `BP_XProfile_Query`
 doesn't extend this class, though my hope is that it eventually will.

 Supports the same compare operators as `BP_XProfile_Query` except
 `'EXISTS'` and `'NOT EXISTS'` because those operators rely on JOINs and I
 don't really think we need them.  If we do need `'EXISTS'` / `'NOT
 EXISTS'`, I'll do up another patch.

 Still need a bit of feedback from comment:4 regarding the `'override'`
 approach that I've chosen to adopt.  I might need to write a few more unit
 tests that shows off the problem.  But, I think we're in a better spot
 then before.
