Fix registration of same method signature via SetFunction (dynamicexp…

…resso#231)

* Properly return all the possible overloads if no overload is an exact match.
Fixes dynamicexpresso#159

* Added a way to remove identifiers from the current interpreter.

* SetFunction now only keeps the latest delegate registered with a given signature (ie. it's no longer possible to register two delegates with the exact same signature).

* Fix broken test.

Change project target frameworks. (dynamicexpresso#225)

Fix dynamicexpresso#224

Lazy compile expression in Lambda (dynamicexpresso#219)

Lazy compile expression in Lambda class to avoid compilation when is not needed.

No longer try to emit a constant expression for generic types with ge…

…neric parameters (e.g. List<T>). (dynamicexpresso#218)

Fixes dynamicexpresso#217

Fix broken lambda parsing. (dynamicexpresso#198)

Fix dynamicexpresso#197

Allow explicit return type object (dynamicexpresso#186)

* No longer omit the conversion expression when the return type is explicitly object.
Force the return type of a lambda expression to typeof(void) to prevent the emission of a conversion expression.
Fixes dynamicexpresso#185

* Remove PrepareDelegateInvoke to avoid modifying the arguments list.

Improve generic type parsing and referencing (dynamicexpresso#178)

* Fix issue with error message.

* Improve generic type parsing, so that the same type can be registered with different Arity.
Properly parse constructor invocation of a generic type.

* Added test with named generics with arity.

* Fix CloseCurlyBracketExpected format.

Improve type parsing to support arrays and generics (dynamicexpresso#173

)

* ?. and ?[ operators now use the existing GenerateNullableTypeConversion that ensures a nullable type isn't converted to a nullable of nullable.
Fixes dynamicexpresso#169

* Promote operands before generating the equality check on ?. and ?[ operators.

* No longer consider ?. and ?[ as tokens, because it prevents the proper parsing of an array of a nullable type (e.g. int?[]).

* Improve type parsing to support arrays and generics.
Fixes dynamicexpresso#172

* No longer consider ?. and ?[ as tokens, because it prevents the proper parsing of an array of a nullable type (e.g. int?[]).

* Improve type parsing to support arrays and generics.
Fixes dynamicexpresso#172

Using ?. and ?[ operators with nullable types (dynamicexpresso#171)

* ?. and ?[ operators now use the existing GenerateNullableTypeConversion that ensures a nullable type isn't converted to a nullable of nullable.
Fixes dynamicexpresso#169

* Promote operands before generating the equality check on ?. and ?[ operators.

Change return type of ?. operator to nullable types (dynamicexpresso#165

)

* If the return type of a ?. operation is a value type, we should convert it to the corresponding nullable type.
Fixes dynamicexpresso#164

* Leverage generic SetVariable.
