---------------------------------------
Summary: Truncated Normal Distribution
Key: STATISTICS-27
URL: https://issues.apache.org/jira/browse/STATISTICS-27
Project: Apache Commons Statistics
Issue Type: New Feature
Reporter: Marko Malenic
This involves a new class added to distribution which implements a truncated
normal distribution.
This is like the normal distribution, except values are bounded to a maximum or
minimum (or both), unlike the normal distribution whose domain is infinite.

Implementation would be similar to how NormalDistribution is already structured.
There's a few ways to generate numbers, some of which are faster than others.
Inverse transform sampling could be used for simplicity.
