Limited set of read/write routines for Nastran bulk data

Collection of tools for reading/writing Nastran bulk data.

The functions provided by this module can be accessed by just importing the “nastran” package. For example, you can access the rdgrids() function in these two ways:

>>> from pyyeti import nastran
>>> from pyyeti.nastran import bulk
>>> bulk.rdgrids is nastran.rdgrids
