(*Context for method definitions*)

(*It is desirable to have a separate namespace for methods.  Otherwise: If classes are defined in *different* packages, and if each package Protects the symbols in its context, then, if these classes have a member name in common, a shadowing and/or protection conflict will arise.*)
(**)
(*This context *must* be visible at user level in $ContextPath for access to methods.*)
(**)
(*Note therefore that usage messages should *not* be defined for the methods in any context *before* he method is declared with DeclareClass, which will properly establish the symbol in the methods context.*)
