public interface BasePropExpressionVisitor<R>

Visitor that can only handle single property values. This interface is extended for visitors that handle a wider set of PropExpressions. * All PropExpressions have to implement an accept method for this interface so we can't add new PropExpression types without adding it to some sub-interface or extending an existing type of PropExpression. Code that we want to to be updated when new types of expression are added should implement the sub-interface so that this requirement is explicit. This base-interface only exists so that the PropertyTag can count as a PropExpression while still allowing this package to operate without the rest of the expression code.
