示例1: SetVariable
/// <summary>
/// Constructs a DLR Expression tree representing setting a variable inside a context.
/// </summary>
/// <param name="runtime"></param>
/// <param name="variableContainer">The container where the lookup should be performed</param>
/// <param name="contextParts">
/// Contains 2 strings:
/// 1. The name of the context
/// 2. The name of the variable inside the context
/// </param>
/// <param name="value">Expression containing the value of the variable</param>
/// <remarks>
/// The returned DLR Expression tree will try to fetch the context inside the container.
/// If the context does not exists, this will result an exception.
/// If the exception occured, the context will be created inside the catch block.
/// After this the context surely exists, so we can simply set the variable to the provided value.
///
/// </remarks>
/// <returns>>Expression tree for setting a value for the given context parts</returns>
