Blurb::
Specify text file containing candidate design points

Description::
Enables text file import of user-specified design points (i.e. configuration
variables). No model responses should be included. Each row should correspond 
to a single design or configuration.

<b> Default Behavior </b>

Be default, methods do not import points from a file.

<b> Usage Tips </b>

Dakota parses input files without regard to whitespace, but the
import_build_points_file must be in one of three formats:
\li \c annotated (default)
\li \c custom_annotated
\li \c freeform
