Created COMMITTERS.md file

#8 earlier pull request, addressed all comments from there. 
This is still a little weird to me for a public repo.  However, if we do want to be transparent about using JIRA internally to track issues also seen on github we could word it something like what I have below.  With the current statement it would be difficult for me to know the JIRA is for Cerner only.

```markdown
  2. Cerner will internally log a JIRA under the following 2 conditions:

    1. If we think there needs to be internal discussion on the topic.
    2. We may create an internal review to ensure quality code before showing it to the world.
```

 (In my example I tried to use markdown syntax, which is why the list is red)
