A NAMESPACE file defines the functions, classes, and methods that are imported into the namespace, and exported for users.
In the following section we describe what Bioconductor reviewers will be looking for in this file.
Exported functions should use camel case or underscoring and not include
., which indicates S3 dispatch.
importFrom() is encouraged over importing an entire package.
However, if there are many functions from a single package,
import() can be acceptable.
