Alpha Pre-Release v0.2

This release adds new features of initialization and installation offline

If you would like to install software using 'apt/yum' locally and transmit local newly created layer to one new machine(i.e, the runtime environment, similar to Singularity), you will get this feature in next release.

Currently, LPMX could package downloaded docker image from docker hub and load it locally, you could not install any software inside the containerized os if you do not have network access in the runtime environment.
