v0.7.0-SNAPSHOT

Moved source across to `src/main/java` we don’t have any Groovy left for a while now
Removed `using` block (and fixed tests)
Tap indexes are now from 0
removed `streamIndex` and `unfilteredIndex` (use tap now)
removed `isExhausted` (use `stream.hasNext()`)
Next up, zip so we can cross the streams ;-)
Added filterWithIndex, flatMapWithIndex, mapWithIndex and untilWithIndex
Added filterWithIndex test
Added tapWithIndex and tapEveryWithIndex

tap and tapEvery now send the object to the closure, NOT the index
to get the index, you need tapWithIndex and tapEveryWithIndex
And the index is the second param of the closure

This is to being it in line with the other *WithIndex methods
Removed debug from Map test
Added stream.skip(n)
Added license
WORKAROUND: Groovy sometimes picks the wrong take method, needs investigation
forgot the import
Try and get clean travis output
Removed Delegatable (no longer used since 'using' removal)
Added transpose and transposeWithIndex.  Needs more testing
Transpose -> Zip
Generics fun
Fix map generator generics for CompileStatic
formatting

to soothe my ocd
Correct generic signature on the extensions for Map.toStream()
Formatting, unused imports, and final properties
Check extra static compilation steps
Added stream.concat( Iterator<T> )
