is.empty

Rails-inspired helper that checks if vector values are "empty",
 i.e. if it's: <code>NULL</code>, zero-length, <code>NA</code>, <code>NaN</code>,
 <code>FALSE</code>, an empty string or <code>0</code>.
 Note that unlike its native R <code>is.&lt;something&gt;</code> sibling functions,
 <code>is.empty</code> is vectorised (hence the "values").

Lightweight utility functions used for the R package
development infrastructure inside the data integration centers ('DIZ')
to standardize and facilitate repetitive tasks such as setting up a
database connection or issuing notification messages and to avoid
redundancy.
