Write MCNP Material Cards
Here we load a test reactor and write each component of one fuel block out as MCNP material cards.
Normally, code-specific utility code would belong in a code-specific ARMI plugin. But in this case, the need for MCNP materials cards is so pervasive that it made it into the framework
