Open Spec File Dialog
The Open Spec File Dialog lists all the files contained in the Specification file, organized by file type.

- The tabs in the View File Types: and View Structures: bars at the top of the dialog allow the user to view a subset of the data files by clicking on a specific file or structure type.

- Checkboxes on the left indicate which files will be loaded once the Load button, in the lower right, is pressed. All files are selected by default. Toggle off a checkbox to keep those files from being loaded. To check or uncheck all the files, click All or None in the Select Files: bar near the top of the dialog.

- The Data Type, Structure, and Data File Name headers can also be clicked to sort the list of files by these attributes.

- The More gear buttons to the right of each checkbox will, once implemented, allow the user to select options to Set the Structure for a file (e.g. Cerebellum, Cortex Left, etc.) or to View Metadata associated with the file. Clicking on these buttons now, will display these options as greyed out, indicating that this feature is not yet implemented.
