#property_value(prop_name) ⇒ Object

gets the value of a property. The property name can be given in several ways. suppose we are trying to get the property ‘Iteration Number’ as in mingle

1) give the name as seen card.property_value(‘Iteration Number’)

2) give the property method name i.e. in the active resource object it would become by default ‘cp_iteration_number’ attribute unless set differently in Mingle

3) give the method a ‘space separated’ / ‘camelcased’ method name. e.g. - ‘Iteration Number’ ‘IterationNumber’
