Original report (archived issue) by Chris Billington (Bitbucket: cbillington, GitHub: chrisjbillington).
Opening an HDF5 file or text file should be done with common functions in labscript_utils rather than code duplication across each program that does it.
If there is an error or no external program is configured in labconfig, this function should be able to pop up a dialog prompting the user to pick a text editor or help it find the path to HDFview (or prompting them to install HDFview). It should then write their choice to labconfig.
