optionally use env vars to read ID & Key & region #9
Description
See #8 for context
@riyasingh87 thanks for pointing that out - it would be great to able to run livetail from any directory. I've added it to my PATH and added a workaround function for now:
livet() { echo $SL_REGION | livetail -i $SL_ACCESS_ID -k $SL_ACCESS_KEY $@ }
