5005d1173c PairNeuronDouble should not implement Comparable. 
As the purpose was only to sort neurons according to an associated
value, using an explicit comparator is simpler. Implementing Comparable
induces also implementing equals and hashcode which are not really
meaningful. They are nevertheless required by our code quality checking
tools.

85a20b5023 Added a nth order Brent solver for general real fields. 
This solver replaces the former solver that was restricted to
Dfp fields only.

1130658baf Fixed findbugs warning. 
When defining compareTo, we should also define equals and hashcode.

3f68627209 Avoid a false positive findbugs warning. 
Findbugs is confused by constant 1.570796251296997 which is a
intentionally slightly offset from PI/2 as per Cody Waite arguments
reduction.

93f8d0e237 Avoid a false positive findbugs warning. 
The source code tests an angle using "angle > (FastMath.PI - 1.0e-10)".
As the compiler does the subtraction of the constants directly, findbugs
complains about a "Rough value of Math.PI found: 3.141592653489793".

bf7e9d505a Fixed checkstyle warnings. 
These warnings correspond to redundant modifiers (public, static, ...).
They are identified by recent versions of checkstyle, in particular the
one shipped with Eclipse. They are not detected by our
maven-checkstyle-plugin yet because it is not the latest one and still
depends on an older version of checkstyle.

73351b6adb code cleanup in GeometricDistribution.java as proposed by Gilles: 
* removed needless declaration of a local variable "p" with the same
value as the "probabilityOfSuccess" field
* remove needless local variable "ret" ("return" statements can be used
directly in each way of the alternatives)
