Returns True if a given attribute exists or False otherwise.
There are two versions of the call - .exists is used with a single attribute and .exists_many (rather than .exist) is used with multiple attributes. Performance-wise, it is more efficient to use .exists_many if more than one attribute should be checked.
session.attr.exists(self, name)

Checks if attributes from the input list exist. A dictionary of boolean flags is returned for each input attribute name.
