/**
* CCodeModel is the base class for model classes that are used to generate code.
*
* Each code generator should have at least one code model class that extends from this class.
* The purpose of a code model is to represent user-supplied parameters and use them to
* generate customized code.
*
* Derived classes should implement the {@link prepare} method whose main task is to
* fill up the {@link files} property based on the user parameters.
*
* The {@link files} property should be filled with a set of {@link CCodeFile} instances,
* each representing a single code file to be generated.
*
* CCodeModel implements the feature of "sticky attributes". A sticky attribute is an attribute
* that can remember its last valid value, even if the user closes his browser window
* and reopen it. To declare an attribute is sticky, simply list it in a validation rule with
* the validator name being "sticky".
*
* @property array $templates A list of available code templates (name=>directory).
* @property string $templatePath The directory that contains the template files.
* @property string $stickyFile The file path that stores the sticky attribute values.
