The `start services` and `stop services` command aliases now map to the
same command as `start maxscale` and `stop maxscale`. This should help
alleviate the confusion that the command naming caused.
The yargs framework combined with the pkg packaging causes the executable
name to be mangled on installation. For this reason, the usage should be
explicitly added to each command.
Making the core a module proved to bring more problems than it solved. For
the sake of simplicity in installation and code coverage reporting, the
core is now completely contained in the `lib/` directory.
Also added preliminary coverage reporting with nyc.
Minor refactoring to the core library to allow multiple calls from within
the same program.
Added --quiet option to silence output so that tests aren't so
verbose. Currently this only works on UNIX based systems.
All invocations into the common helper functions are now done through the
`maxctrl` function. This allows the program arguments to be passed to the
core as a parameter instead of reading them from global variables.
This helps with the implicit initialization that was done when the yargs
library was required which caused duplicated output.
Refactored the core functions so that they only process the argument
vector. The parsing of the argument vector is done in maxctrl.js where it
is more appropriate.
