-	- Modified HiddenField Check to allow field shadowing on Constructor, Setter
-	and Abstract Method parameters.
-	- Modified StaticVariableName Check format for PUBLIC variables from ^[a-z][a-zA-Z0-9]*$
-	to ^[A-Z_]*$ . Others (protected, package and private) still have ^[a-z][a-zA-Z0-9]*$
-	- Modified the severity of the following Checks from error to info:
-	• JavadocPackage (checks for package-info.java)
-	- Modified the severity of the following Checks from error to warning and the scope from private to protected:
-	• JavadocType (class and interface declarations)
-	• JavadocMethod (method declarations)
-	• JavadocVariable (variable declarations)
-	• JavadocStyle (Javadocs are "well formed")
-	- Modified the severity of the following Checks from error to warning because not so critical:
-	• LineLenght (the default value is 80 which is also used in formatter, but
-	i.e. member declarations are not wrapped onto next line)
-	• RedundantModifier (i.e. using public in interface method declarations)
-	• RedundantThrows (causes unnecessary fails when can't get class information)
-	• MethodLength (default maxLength is 150)
-	• ParameterNumber (default maxLength is 7)
-	• EmptyBlock (if-else statements have some blocks if x -> no action)
-	• UpperEll (should use L instead of l with long)
-	• TodoComment (not serious)
-	• WhitespaceAroundCheck (expects whitespace around some operators)
-	NOTE other checks are also warning but should be error.
-	- Modified the severity of the following Checks from error to ignore:
-	• FinalParameters (method parameters can be modified)
-	• VisibilityModifier (i.e. in state classes public members are allowed)
-	• DesignForExtension (this design is not used)
-	• FileLength (bad design to have files with over 2000 lines? see VScrollTable)
-	• MagicNumber (MagicNumbers like error codes are used, but could just ignore
-	this in some classes)
-	• AvoidInlineConditionals ( you like these ? ignore : error ) -->
