Title: Review: Field3D build and minor implementation fixes

* Add FIELD3D_HOME build variable to allow explicit path to Field3D implementaiton
* Early out when "opening" a f3d file that doesn't exist (prevents the Field3D library
from spewing error messages to the terminal.
* Properly catch exceptions thrown by Field3D open.
* (SPI only -- set up where to find f3d in our environment)
