Detailed Description
By subclassing QQmlCustomParser, you can add a parser for building a particular type.
The subclass must implement compile() and setCustomData(), and register itself in the meta type system by calling the macro:
QML_REGISTER_CUSTOM_TYPE(Module, MajorVersion, MinorVersion, Name, TypeClass, ParserClass)

void QQmlCustomParser::error(const QV4::CompiledData::Location &location, const QString &description)
Reports an error with the given description.
An error is generated referring to the location in the source file.

int QQmlCustomParser::evaluateEnum(const QString &script, bool *ok) const
If script is a simple enumeration expression (eg. Text.AlignLeft), returns the integer equivalent (eg. 1), and sets ok to true.
Otherwise sets ok to false.
A valid ok must be provided, or the function will assert.

const QMetaObject *QQmlCustomParser::resolveType(const QString &name) const
Resolves name to a type, or 0 if it is not a type. This can be used to type-check object nodes.
