Source code for webnotes.model.code

"""
This is where all the plug-in code is executed. The standard method for DocTypes is declaration of a 
standardized `DocType` class that has the methods of any DocType. When an object is instantiated using the
`get_obj` method, it creates an instance of the `DocType` class of that particular DocType and sets the 
`doc` and `doclist` attributes that represent the fields (properties) of that record.

methods in following modules are imported for backward compatibility

	* webnotes.*
	* webnotes.utils.*
	* webnotes.model.doc.*
	* webnotes.model.doclist.*
