Fixed a bug where CPExpression_set was evaluating to an expression instead of a set.
Replaced parsing exceptions with a generic function indicating where it failed.
Added missing getters in CPExpression.
Added a type: argument to FunctionExpression initializer used by subclasses to init super with their own type.
Fixed evaluation with bindings dictionary in CPExpression_variable. Allow values in bindings to be a constant or an expression (per cocoa).
Tests: added tests for subqueryExpressions, for variableExpression evaluation where the value in the bindings dictionary can be either a constant or another expression.
Parsing a simple variable expression works (e.g. '$x = 12'), parsing a variable in a combined path (e.g.
'$x.path = 12' won't yet.
Parsing: fixed typos in built-in function names, fixed support for [FIRST], [LAST], [INDEX]
Fixed aggregates {exp1,exp2}
Fixed -expressionForFunction:selectorName:arguments:
built-in functions are now class methods
Cleaned a lot of code in built-in functions
EvaluatedObjectExpression is now a singleton
Merged inserset/minus/union Set into one file
Deleted unused expression subclasses : expression_operator and expression_assignement
Added CPCoding methods and changed key names to match Cocoa
Made KeyPathExpresion a subclass of FunctionExpression like in Cocoa
