Open.Evaluation is a framework for constructing and evaluating any hierarchal formula or complex structure. Typically used for evaluating math or algorithms.
This set of interfaces and classes can be used to create serializable (human readable) functions for use with other systems that require a reproducable structure.
For example: Given a specific mathmatical formula (or function), it is possible to not only resolve/evaluate the result given a set of parameters, it is also possible to inspect the formula's structure and see how the values are being used.
(See Core/EvaluationBase.cs)
The main idea here is to envorce immutable classes and related sub classes. No changes allowed after construction. A clone can only be created by 'recreating' or 'reconstructing'.
It is very important to maintain this since these classes should not change during operation.
To avoid potential memory problems, all heirarchies should be unidirectional: "The parent is aware of the children, but the children are unaware of the parent." This allows for child sharing and has the potential to signficantly reduce the memory footprint.
