An expression chain builder is an object which supplies various operator<< overloads which build chains of Expression Templates by prepending the templated ExpressionType to the source.

An expression chain builder is an object which supplies various operator<< overloads which build chains of Expression Templates by prepending the templated ExpressionType to the source.
Note that it is not the expression itself but rather contains all the information to instantiate the expression when a data source is prepended to it. This base class allows to store argument values needed by some expressions. Most expressions don't need that and can just instantiate a constexpr ExpressionChainBuilder instance. Others should create an instance using makeExpressionChainBuilderWithRuntimeArgs.
