/**
* CWsdlGenerator generates the WSDL for a given service class.
*
* The WSDL generation is based on the doc comments found in the service class file.
* In particular, it recognizes the '@soap' tag in the comment and extracts
* API method and type definitions.
*
* In a service class, a remote invokable method must be a public method with a doc
* comment block containing the '@soap' tag. In the doc comment, the type and name
* of every input parameter and the type of the return value should be declared using
* the standard phpdoc format.
*
* CWsdlGenerator recognizes the following primitive types (case-sensitive) in
* the parameter and return type declarations:
* <ul>
* <li>str/string: maps to xsd:string;</li>
* <li>int/integer: maps to xsd:int;</li>
* <li>float/double: maps to xsd:float;</li>
* <li>bool/boolean: maps to xsd:boolean;</li>
* <li>date: maps to xsd:date;</li>
* <li>time: maps to xsd:time;</li>
* <li>datetime: maps to xsd:dateTime;</li>
* <li>array: maps to xsd:string;</li>
* <li>object: maps to xsd:struct;</li>
* <li>mixed: maps to xsd:anyType.</li>
* </ul>
*
* If a type is not a primitive type, it is considered as a class type, and
* CWsdlGenerator will look for its property declarations. Only public properties
* are considered, and they each must be associated with a doc comment block containg
* the '@soap' tag. The doc comment block should declare the type of the property.
*
* CWsdlGenerator recognizes the array type with the following format:
* <pre>
* typeName[]: maps to tns:typeNameArray
* </pre>
*
* The following is an example declaring a remote invokable method:
* <pre>
* / **
* * A foo method.
* * @param string name of something
* * @param string value of something
* * @return string[] some array
* * @soap
* * /
* public function foo($name,$value) {...}
* </pre>
*
* And the following is an example declaring a class with remote accessible properties:
* <pre>
* class Foo {
* / **
* * @var string name of foo
* * @soap
* * /
* public $name;
* / **
* * @var Member[] members of foo
* * @soap
* * /
* public $members;
* }
* </pre>
* In the above, the 'members' property is an array of 'Member' objects. Since 'Member' is not
* a primitive type, CWsdlGenerator will look further to find the definition of 'Member'.
