RulesEngine
Rules Engine is a package for abstracting business logic/rules/policies out of the system. This works in a very simple way by giving you an ability to put your rules in a store outside the core logic of the system thus ensuring that any change in rules doesn't affect the core system.

## v3.0.0 - Major feature release
The version contains a lot of fixes and improvements and hopefully as-little-as-possible breaking changes.
### **FastExpressionCompiler** and **FastExpressionCompiler.LightExpression**
- Performance and memory consumption is improved, especially for the expressions with the closure and for expressions with the nested lambdas.
- Filled the gaps in the expressions support.
- Many fixes in the IL emit.
- Adds `ToCSharpString()` to output the compile-able C# code described by the expression (tries hard).
- Adds `ToExpressionString()` to output the valid expression construction syntax, so given an expression object you'll get e.g. `Lambda(New(...))`.
- Adds optional `enum CompilerFlags { Default, NoInvocationLambdaInlining, EnableDelegateDebugInfo}` parameter for the compilation
- `EnableDelegateDebugInfo` adds the diagnostic info into the compiled delegate including its source Expression and C# code. Can be used as following:
```cs
var f = e.CompileFast(true, CompilerFlags.EnableDelegateDebugInfo);
var di = f.Target as IDelegateDebugInfo;
Assert.IsNotNull(di.Expression);
Assert.IsNotNull(di.ExpressionString);
Assert.IsNotNull(di.CSharpString);
```
### **FastExpressionCompiler.LightExpression**
- Now includes the `ExpressionVisitor`.
- Improves the compatibility (the drop-in replacement) between `FastExpressionCompiler.LightExpression.Expression` and `System.Linq.Expression`.
- Decreasing the memory consumed by the created expressions, plus implementing the `IArgumentProvider` and `IParameterProvider` for some of the expressions.
