Three handy predicates to check classpath

[da-tubi]

README preview: https://github.com/darcy-shen/enableIf.scala/tree/feature/enableWithClasspath2

The original idea of checking classpath in enableIf comes from @Renkai

closes #57

You forgot import

You forgot import

No, import enableIf._ imports it.

[Atry]

The import should be put in the quasiquote

[da-tubi]

I don't know how to import in the quasiquote. I decide to evaluate it. Now, in macro, the two handy functions only accept String/Regex literals. And now, it only supports @enableIf. I'm waiting for your reply on the current impl. If it is OK, let me make it work for @enableMembersIf and polish the docs.

Thanks for the review! I will complete this PR tomorrow with three handy functions on the two existing macros:

• classpathMatches
• classpathMatchesArtifact
• classpathMatchesScalaArtifact

Just like this

q"""
import ...
${you code here}
"""

Cool, it works. I just tested it. Let me complete the PR now!

@Atry Please review it again. This pr is complete now!

@Atry Here is final handy func combos:

• classpathContains
• classpathMatches
• classpathMatchesArtifact(aid, version)
• classpathMatchesArtifact(crossScalaBinaryVersion(aid), version)

Looks good. Thank you!
