A file object for MDV data.
A MdvFile object stores metadata and data from a MDV file. Metadata is stored in dictionaries as attributes of the object, field data is stored as NumPy ndarrays as attributes with the field name. By default only metadata is read initially and field data must be read using the read_a_field or read_all_fields methods. This behavior can be changed by setting the read_fields parameter to True.
