/**
* 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 {nillable=1, minOccurs=0, maxOccurs=2}
* * @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'.
*
* Optionally, extra attributes (nillable, minOccurs, maxOccurs) can be defined for each
* property by enclosing definitions into curly brackets and separated by comma like so:
*
* {[attribute1 = value1][, attribute2 = value2], ...}
*
* where the attribute can be one of following:
* <ul>
* <li>nillable = [0|1|true|false]</li>
* <li>minOccurs = n; where n>=0</li>
* <li>maxOccurs = n; where [n>=0|unbounded]</li>
* </ul>
*
* Additionally, each complex data type can have assigned a soap indicator flag declaring special usage for such a data type.
* A soap indicator must be declared in the doc comment block with the '@soap-indicator' tag.
* Following soap indicators are currently supported:
* <ul>
* <li>all - (default) allows any sorting order of child nodes</li>
* <li>sequence - all child nodes in WSDL XML file will be expected in predefined order</li>
* <li>choice - supplied can be either of the child elements</li>
* </ul>
* The Group indicators can be also injected via custom soap definitions as XML node into WSDL structure.
*
* In the following example, class Foo will create a XML node &lt;xsd:Foo&gt;&lt;xsd:sequence&gt; ... &lt;/xsd:sequence&gt;&lt;/xsd:Foo&gt; with children attributes expected in pre-defined order.
* <pre>
* / *
* * @soap-indicator sequence
* * /
* class Foo {
* ...
* }
* </pre>
* For more on soap indicators, see See {@link http://www.w3schools.com/schema/schema_complex_indicators.asp}.
*
* Since the variability of WSDL definitions is virtually unlimited, a special doc comment tag '@soap-wsdl' can be used in order to inject any custom XML string into generated WSDL file.
* If such a block of the code is found in class's comment block, then it will be used instead of parsing and generating standard attributes within the class.
* This gives virtually unlimited flexibility in defining data structures of any complexity.
* Following is an example of defining custom piece of WSDL XML node:
* <pre>
* / *
* * @soap-wsdl <xsd:sequence>
* * @soap-wsdl <xsd:element minOccurs="1" maxOccurs="1" nillable="false" name="name" type="xsd:string"/>
* * @soap-wsdl <xsd:choice minOccurs="1" maxOccurs="1" nillable="false">
* * @soap-wsdl <xsd:element minOccurs="1" maxOccurs="1" nillable="false" name="age" type="xsd:integer"/>
* * @soap-wsdl <xsd:element minOccurs="1" maxOccurs="1" nillable="false" name="date_of_birth" type="xsd:date"/>
* * @soap-wsdl </xsd:choice>
* * @soap-wsdl </xsd:sequence>
* * /
* class User {
* / **
* * @var string User name {minOccurs=1, maxOccurs=1}
* * @soap
* * /
* public $name;
* / **
* * @var integer User age {nillable=0, minOccurs=1, maxOccurs=1}
* * @example 35
* * @soap
* * /
* public $age;
* / **
* * @var date User's birthday {nillable=0, minOccurs=1, maxOccurs=1}
* * @example 1980-05-27
* * @soap
* * /
* public $date_of_birth;
* }
* </pre>
* In the example above, WSDL generator would inject under XML node &lt;xsd:User&gt; the code block defined by @soap-wsdl lines.
*
* By inserting into SOAP URL link the parameter "?makedoc", WSDL generator will output human-friendly overview of all complex data types rather than XML WSDL file.
* Each complex type is described in a separate HTML table and recognizes also the '@example' PHPDoc tag. See {@link buildHtmlDocs()}.
