Remove examples directory; these now live in gf-contrib

All changes have been reflected in the gf-contrib repository:
https://github.com/GrammaticalFramework/gf-contrib

Now, for WebSetup to build the example grammars, one must have gf-contrib
cloned in the same top-level directory as GF. When this isn't the case,
WebSetup displays a notice without failing.

---1 An Abstract Syntax for Business and Love Letters
---
--- This file defines the abstract syntax of a grammar set whose concrete syntax
--- has so far been written to five languages: English, Finnish, French, Russian,
--- and Swedish. 
---
--- The main category of the grammar is $Letter$. The other categories are
--- parts of the letter.

--- The heading consists of a greeting of the recipient. The $JustHello$
--- function will actually suppress the name (and title) of the recipient,
--- but the $Recipient$ argument keeps track of the gender and number.

-  PlainRec  : Recipient -> Heading ;
-  HelloRec  : Recipient -> Heading ;
-  JustHello : Recipient -> Heading ;
-
--- A message is a sentence with of without a *mode*, which is either 
--- regret or honour.
-
-  ModeSent  : Mode -> Sentence -> Message ;
-  PlainSent : Sentence -> Message ;
-
-  Honour, Regret : Mode ;
-
--- The ending is either formal or informal. It does not currently depend on
--- the heading: making it so would eliminate formality mismatches between
--- the heading and the ending.
-
-  FormalEnding   : Author -> Ending ;
-  InformalEnding : Author -> Ending ;
-
--- The recipient is either a colleague, colleagues, or darling.
--- It can also be a named person. The gender distinction is made
--- because there are things in the body of the letter that depend on it.

-  ColleagueHe, ColleagueShe   : Recipient ;
-  ColleaguesHe, ColleaguesShe : Recipient ;
-  DarlingHe, DarlingShe       : Recipient ;
-
-  NameHe, NameShe : String -> Recipient ;
-
--- For the author, there is likewise a fixed set of titles, plus the named author.
--- Gender distinctions could be useful even here, for the same reason as with
--- $Recipient$. Notice that the rendering of $Spouse$ will depend on the
--- gender of the recipient.
-
-  President, Mother, Spouse, Dean : Author ;
-  Name      : String -> Author ;
-
--- As for the message body, no much choice is yet available: one can say that
--- the recipient is promoted to some position, that someone has gone bankrupt,
--- or that the author loves the recipient.
