Blurb::
Specify how the random field will be built:
from a data file, from simulation
runs, or from a covariance matrix.
THIS IS AN EXPERIMENTAL CAPABILITY.
Description::
As part of the capability to generate a random field representation, the user
needs to specify the data used to generate the random field representation.
This data may reside in a data file, it may be generated by running a set of simulations and generating field responses, or it
may be generated by a covariance matrix defined over a mesh.
THIS IS AN EXPERIMENTAL CAPABILITY UNDER ACTIVE DEVELOPMENT.

*Default Behavior*
Currently, the ``build_source`` that is fully working is the
``dace_method_pointer``.  The others are not fully operational.
