Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method_name, *args, &block) ⇒ Object

from the input data. If an operation is attempted, then @op_value should be checked to see if the operation is valid for it, not necessarily the potentially string @value
