+ Updated method used to aquire App Bundle Version
+ Fixed various issues found after further testing for Matlab 2017b
- Remove the argument '-mode silent' from install line; added it back to the installer_input file
+ The 'staging' method from the last revision for the network.lic file did not work, as Matlab does not 'look' for it until it's first launch, which, at that time, the network.lic file is gone (it's pointing to the tempoary unpack directory of the pkg)
+ No longer staging the files on the disk; now are only kept in the tempoary unpacked package 'Scripts' directory
+ Added code to add the location of the of the unpacked license.nic file to the install_input file before installing
