Classes
class	PredicateExpression
	This class defines an expression that can be used in building a predicate, either alone or in conjunction with other expressions. Each expression consists of a variable name, which is the source of the data to be compared (ie: column name, property name, whatever), an operator (>, <, etc), and a comparison value. More...
class	PredicateSet
	This class defines a structure for creating a set of predictate expressions, such as would be used when composing a 'where' clause in a database query or an XPath qualifier. It is basically a simplified List{PredicateExpression} implemenation that allows iteration and some special methods for adding expressions. More...
class	WhyBool
	WhyBool is a boolean implementation that allows the user to attach a reason for the boolean value. It has been overloaded to allow quick comparison with true System.Boolean values. Using this type of value as a return value from validation-type routines can help keep program flow control from creeping into exception handlers and prevent the need for 'ref' parameters to store the reason for the boolean value.
