submodule updates fail

[nickcounts]

While attempting to build this project, the submodule update process fails on GFS_CI.git

Cloning into 'apps/ci'...
Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
fatal: clone of 'git@github.com:nasa/CFS_CI.git' into submodule path 'apps/ci' failed

It looks like the recent commit in .gitmodules added new apps and used ssh instead of HTTPS. I presume changing them to the form of

[submodule "apps/to"]
	path = apps/to
	url = https://github.com/nasa/CFS_TO.git
[submodule "apps/ci"]
	path = apps/ci
	url = https://github.com/nasa/CFS_CI.git
[submodule "apps/io_lib"]
	path = apps/io_lib
	url = https://github.com/nasa/CFS_IO_LIB.git

will prevent this issue for others.
