Use a relative filepath for the define_regions attribute
Use a relative filepath for the define_regions attribute

The *find_simulation_input_file* utility returns an absolute path
to a file. I passed its output directly into the `define_regions`
attribute of the **bmi_ilamb.yaml** file. This absolute path is
invalid on the WMT executor. A relative file needs to be used instead.
