// This lets you get the name of a field as a string.
// When calling BOReader or other things that require string names, the compiler can't

// Also, schema changes will make the code fail to compile so you upgrades are simpler!

// Saddly it does require linq.

// Get the name of a static or instance property from a property access lambda.

// <returns>The name of the property</returns>
