Version 0.4.0 release candidate 0

This is the first release candidate for neurodocker version 0.4.0, which adds support for generating Singularity recipes (and involves a near complete rewrite of neurodocker).

Dockerfiles and Singularity files are generated from templates of installation instructions.

Users of this release may notice that features may be have dropped while converting from the old class-based to the new template-based framework. This is not intentional in most cases, so please submit an issue if a feature that you use has been lost.

Additions

• Singularity recipes can now be generated.
• Matlab Compiler Runtime can be installed independently.

Breaking changes

• CLI for generate commands follows the syntax neurodocker generate docker/singularity
• FreeSurfer license file option is removed. License files should be added at container runtime.
• --spm becomes --spm12

Fixes

• SPM12 takes a specific version release now and does not install dev unless the user requests it.
