Fix assertion on vect count to <=10.
Failed with ==10 when test run under Eclipse.
Now matches the same check on line 275.
Fix bug in abs(float) that was changing the sign of zero (0 became -0).
This unexpected behavior conflicts with the behavior of Math.abs.
While applying this fix, I found several other methods which should
also just delegate to their corresponding Math functions.
Restore the "inline" definitions of min, max, and signum.
Bill convinced me that the Math versions can truly be performance
bottlenecks, and the behavior with NaN is not important.
Keeping the delegated versions of abs for the moment because
adding a sign to zero is not acceptable. Will address separately.
Restore and correct the inline definitions of abs.
abs(0.0d) and abs(0.0f) now correctly return 0 rather than -0.
However, change the test so that abs(-0) is allowed to return -0.
Do not delegate to Math.abs for performance reasons.
Fix an old typo in the tanh javadoc.
Apply same changes here as to MathPlus.  Fix the sign of abs(0.0).
Javadoc --- point out that abs(-0) does not clear the sign bit.
Fixed rounding-error bug.
Fixed bug in PlotPanelPixels3 for nc=3 or nc=4.
Testing local diffusion kernels.

Require Java SE 7

Fork-join framework is in Java SE 7. So have deleted source for
jsr166y, which required access to restricted apis.
Update scripts for Java SE 7.
Update build for Scala 2.10

Scala builds (enabled if SCALA_HOME is set) now require
scala-reflect.jar.

No substantive changes.
