Bumped version to 0.0.18. Introduced fullCoverage() which is a wrapper for running mclapply() on loadCoverage(cutoff=NULL). Added it because this information is needed in generateReport() and having a function would in theory make it easy for users to then use generateReport(). Fixed R CMD check warnings: there is one remaining related to the Rcpp flags, but even DEseq2 has the same code and is already in BioC, so I guess that it won't matter much.
