Sparse Linear Algebra: complex vectors now override right Equals. gh-20.
Previously sparse vectors for Complex and Complex32 did override
Object.Equals instead of the generic IEquatable<Vector<T>>.Equals.
Now only overrides the generic version to ensure that the right version
is called in all code paths.

Threading: CommonParallel now supports empty loops. Closes gh-19.
CommonParallel did break on empty loops with an argument exception instead
of just doing nothing. It now exits early if there's nothing to do in
For and Invoke, no longer throwing an exception. Also, it now special cases
single-element iterations and inlines their execution (trivial loop
unrolling), skipping all the threading/task overhead.

[Matrix] LeftMultiply with vector is exactly the same as TransposeThisAndMultiplty() with vector
Change LeftMultiply to a protected method (from protected abstract) and it now
calls TransposeThisAndMultiply(). TransposeThisAndMultiply has unit tests
so it was chosen as the "main" method. Overrides of LeftMultiply were removed,
because now only TransposeThisAndMultiply() needs to be overriden.

[Single/Double.Matrix] Remove redundant calculation of abs in frobenius norm
The formulas found in various references do not have abs. Furthermore,
when multiplying A*A^T or A^T*A (for the frobenius norm we only care
about the diagonal so it doesn't matter which product is used) the
i-ith diagonal element of the final matrix comes from the multiplication
of line i with itself. Therefore, all numbers involved will be multiplied
with themselves resulting in numbers that are always non-negative.
