Support doc strings which are specified below the property definition

[VigneshVSV]

A feature that I came across which work well with code editors - it is possible to specify docs or description right below the definition of properties or class attributes, similar to function or method docstring. Somehow, this was not known while creating the docstring attribute.

Syntax:

class MyThing(Thing):

    my_prop = Property(default=5)
    """this is the doc string""" 

    # compared to existing specification
    my_prop2 = Property(default=5, doc="this is the docstring")

Pick up this syntax and fit into the value of doc of the Property.

Rough steps:

• inspect the definition annotation to see where this value is set
• populate said value into the doc variable of property
• verify if code editors pick up, if not, still support the above two steps, lets see what to do later.

Once the doc is set, its automatically picked up the TD/TM generator.
