Option to exclude some files from instrumenting

[dmitryshimkin]

I want to exclude some files from instrumenting. I can't use 'vendors' or 'helpers' because these files should be placed in particular position in code (in my case, after instrumented code)

I have the same problem. I have some JavaScript files that have a lot of configuration that I can't really unit test but I need them to load after the source that I want coverage for.

Just realized that I can include these files under specs so that they load after src but before the real specs....but this is a bit of a hack and won't work in every scenario

Introduced files option in v0.3.1.
