TXLF: TexOS teaching open source

It's actually going to vary a little from state to state and even district to district (in the cut-off ages for starting school, and, in the case of 6th grade, whether that is elementary or "junior high"/"middle school"). The only real salient point is that the project bumped it up to the next age group.

Also, just so everyone is 100% clear, I was not attempting to suggest that HeliOS is dropping the ball or doing a disservice through its own work -- far from it -- I was only observing that I found it interesting that TexOS has a different approach, and one that has value of a different sort.
