be8563a6c5 Fixed findbugs warnings. 
The warnings were related to compareTo implementations not handling -0.0
or NaN properly (cf
<http://findbugs.sourceforge.net/bugDescriptions.html#CO_COMPARETO_INCORRECT_FLOATING>).

04454fc009 Fixed findbugs warning. 
When defining compareTo, we should also define equals and hashcode.

b72d44673c 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.

fae8d86872 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".

2114da384a 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.
