-A PPExpressionParser is a parser to conveniently define an expression grammar with prefix, postfix, and left- and right-associative infix operators.
-
-The following code initializes a parser for arithmetic expressions. First we instantiate an expression parser, a simple parser for expressions in parenthesis and a simple parser for integer numbers.
-
-	expression := PPExpressionParser new.
-	parens := $( asParser token trim , expression , $) asParser token trim 
-		==> [ :nodes | nodes second ].
-	integer := #digit asParser plus token trim
-		==> [ :token | token value asInteger ].
-	
-Then we define on what term the expression grammar is built on:
-
-	expression term: parens / integer.
-	
-Finally we define the operator-groups in descending precedence. Note, that the action blocks receive both, the terms and the parsed operator in the order they appear in the parsed input. 
-	
-	expression
-		group: [ :g |
-			g prefix: $- asParser token trim do: [ :op :a | a negated ] ];
-		group: [ :g |
-			g postfix: ''++'' asParser token trim do: [ :a :op | a + 1 ].
-			g postfix: ''--'' asParser token trim do: [ :a :op | a - 1 ] ];
-		group: [ :g |
-			g right: $^ asParser token trim do: [ :a :op :b | a raisedTo: b ] ];
-		group: [ :g |
-			g left: $* asParser token trim do: [ :a :op :b | a * b ].
-			g left: $/ asParser token trim do: [ :a :op :b | a / b ] ];
-		group: [ :g |
-			g left: $+ asParser token trim do: [ :a :op :b | a + b ].
-			g left: $- asParser token trim do: [ :a :op :b | a - b ] ].
-		
-After evaluating the above code the ''expression'' is an efficient parser that evaluates examples like:
-
-	expression parse: ''-8++''.
-	expression parse: ''1+2*3''.
-	expression parse: ''1*2+3''.
-	expression parse: ''(1+2)*3''.
-	expression parse: ''8/4/2''.
-	expression parse: ''8/(4/2)''.
-	expression parse: ''2^2^3''.
-	expression parse: ''(2^2)^3''.

-A PPCompositeParser is composed parser built from various primitive parsers. 
-
-Every production in the receiver is specified as a method that returns its parser. Note that every production requires an instance variable of the same name, otherwise the production is not cached and cannot be used in recursive grammars. Productions should refer to each other by reading the respective inst-var. Note: these inst-vars are typically not written, as the assignment happens in the initialize method using reflection.
-
-The start production is defined in the method start. It is aliased to the inst-var parser defined in the superclass of PPCompositeParser.!!

-An abstract parser for all parsers in PetitParser. Subclasses implement #parseOn: to perform the actual recursive-descent parsing. All parsers support a variety of methods to perform an actual parse, see the methods in the #parsing protocol. Parsers are combined with a series of operators that can be found in the #operations protocol.
