/** @class Equation
45
* This class stores a string form of a symbolic expression
46
* to be evaluated e.g. for the boundary conditions, the unique
47
* numeric ID of that expression and a reference to the unique
48
* static instance of AnalyticExpressionEvaluator.
49
*
50
* The scenario is that for multiple copies of
51
* Equation class holding their symbolic expressions in the
52
* std::string form, there is a unique instance of
53
* AnalyticExpressionEvaluator which holds a set of pre-processed
54
* symbolic expressions in the form of sequential containers of
55
* execution functors, ready for fast evaluation.
56
*
57
* AnalyticExpressionEvaluator also keeps all constants
58
* and parameters specified in an XML file. There should be
59
* only one copy of Equation class per each symbolic expression
60
* specified in XML file, modulo possible bugs. Classes Equation
61
* and AnalyticExpressionEvaluator live symbiotic in a sense that the
62
* expression id stored in Equation class is generated by
63
* AnalyticExpressionEvaluator which holds ordered container of
64
* pre-processed expressions.
