messages around install

Could remove this anytime...

Warning: The blj_functions library is deprecated.
Warning: It will be removed as of version v1.4.0.

On some systems, you get a message:

Successfully installed BioLockJ version v1.3.16

But on some systems (our own docker build image), you get an error message that the biolockj command is not found. Prevent this other message, even when the still worked correctly.

This bit is pretty good...

Start a new session and run "biolockj --help" to see options.
Then run a small pipeline:
"biolockj $BLJ/templates/myFirstPipeline/myFirstPipeline.properties" 

BUT, I often see people exit their session and start a new one, and run biolockj --help, great; and then they say "what was that next thing I'm supposed to do ? ". They go the user guide and find it, but there is an awkward moment.

• maybe add a url here for the user-guide, just in case they don't already have it up
• maybe add the instructions for the test pipeline to the bottom of the help menu.

branch msgs has changes for

• the error message on some systems
• include the command to run test pipeline at the end of the help menu
• removing the message about blj_functions from the install process (the message is still at the top of blj_functions, which will be removed whenever we reach v1.4.0).
