Description:
This module maintains a concept of a current selection of entropy source.
Algorithms that require entropy, such as those in Data::Entropy::Algorithms, can
use the source nominated by this module, avoiding the need for entropy source
objects to be explicitly passed around. This is convenient because usually one
entropy source will be used for an entire program run and so an explicit entropy
source parameter would rarely vary. There is also a default entropy source,
avoiding the need to explicitly configure a source at all.

If nothing is done to set a source then it defaults to the use of Rijndael (AES)
in counter mode (see Data::Entropy::RawSource::CryptCounter and
Crypt::Rijndael), keyed using Perl's built-in rand function. This gives a data
stream that looks like concentrated entropy, but really only has at most the
entropy of the rand seed. Within a single run it is cryptographically difficult
to detect the correlation between parts of the pseudo-entropy stream. If more
true entropy is required then it is necessary to configure a different entropy
source.
