This package contains classes and interfaces that provide implementation details for the framework.
Typically, an application developer does not need to deal with these classes directly.
This package represents the heart of the framework implementation, so if an application developer
needs to understand the guts of iScreen, this is the package to see. Of particular note is the
ContextBean object, which represents the base root used by both OGNL and MVEL. In addition,
resource (for internationalization support) objects, and validator handling code is contained
within this package.
