register_parser
Description:
Register a parser that can convert Variant data into an instance of a given Type.
Note that you can register more than one parser for the same Type provided that you give them different variant type signatures.
If there is already a parser registered for the given type and vtype it will be silently replaced.
The recommended behaviour is that Object classes register their parsers in their respective class init functions.
Parameters:
| type |
The Type of the object class to register a parser for |
| vtype |
Variants to be converted must have this signature |
| parse_func |
A function to convert Variant data into an instance of the given |
