check for valid version of node / nodejs

[mr-c]

for example, v0.10.25 is too old

if im not wrong, this would require making changes to cwltool/sandboxjs.py https://github.com/common-workflow-language/cwltool/blob/master/cwltool/sandboxjs.py#L33

after successful node detection, we need to check the version and if it's below the threshold, raise a runtime exception and exit the program. probably output a logging message before doing that.

@manu-chroma A good plan, yep!

[manu-chroma]

any threshold version to check against?

currently setting it to v0.10.25

[tetron]

The spec currently sets the minimum at ECMAScript 5.1, which seems to be well supported by Node.js 0.10.25. This is the version that ships in Ubuntu 14.04. Debian 8 ships with Node.js 0.10.29.

There's lots of goodies in ECMAScript 6+, but according to http://node.green/ you want to be using Node.js 6.0 or later to have good compliance with the standards.

We can consider bumping the requirement to ECMAScript 6 in the v1.1 spec.

for the time being, what would you suggest should go in cwltool ?

should we stick to the current specification or set the minimum threshold version to Node.js 6.4.0 ?
i can open an issue in common-workflow-language/common-workflow-language for the same.

relevant PR: #337

@manu-chroma The minimum version to detect should be 0.10.25 as we are not changing the CWL specifications at this time.
