Changes in 0.10.0.0

* Both type classes Mean and Variance are split in two. This
is required for distributions which do not have finite
variance or mean.
* The type classes Mean and Variance are split in two. This is
required for distributions which do not have finite variance or
mean.

* complCumulative is added to type class Distribution in order to assess
accurately probalities P(X>x) which is used in one-tailed tests.
* The S.Sample.KernelDensity module has been renamed, and
completely rewritten to be much more robust. The older module
oversmoothed multi-modal data. (The older module is still
available under the name S.Sample.KernelDensity.Simple).

* stdDev is added to Variance type class for distributions.
* Histogram computation is added, in S.Sample.Histogram.

* Constructor S.Distribution.normalDistr takes standard deviation
instead of variance as parameter.
* Discrete Fourie transform is added, in S.Transform

* Bug in S.Quantile.weightedAvg is fixed. It produced wrong answer if
sample contains only one element.
* Root finding is added, in S.Math.RootFinding.

* Bug in quantile estimations for chi-square and gamma distribution is
fixed.
* The complCumulative function is added to the Distribution
class in order to accurately assess probalities P(X>x) which are
used in one-tailed tests.

* Integer overlow in mannWhitneyUCriticalValue is fixed. It produced
wrong critical value for moderately large samples. Something around 20
for 32-bit machines and 40 for 64-bit ones.
* A stdDev function is added to the Variance class for
distributions.

* Bug in mannWhitneyUSignificant is fixed. If either of samples is larger
than 20 it produced completely wrong answer.
* The constructor S.Distribution.normalDistr now takes standard
deviation instead of variance as its parameter.

* One and two tailed tests in S.Tests.NonParametric are selected with
enumeration types instead of booleans.
* A bug in S.Quantile.weightedAvg is fixed. It produced a wrong
answer if a sample contained only one element.

* Performance improvements for Mann-Whitney U and Wilcoxon tests.
* Bugs in quantile estimations for chi-square and gamma distribution
are fixed.

* sortBy is added to Statistics.Function
* Integer overlow in mannWhitneyUCriticalValue is fixed. It
produced incorrect critical values for moderately large
samples. Something around 20 for 32-bit machines and 40 for 64-bit
ones.

* Mean and variance for gamma distribution is fixed
* A bug in mannWhitneyUSignificant is fixed. If either sample was
larger than 20, it produced a completely incorrect answer.

* Much faster cumulutive probablity functions for Poisson and
hyperheometric distributions.
* One- and two-tailed tests in S.Tests.NonParametric are selected
with sum types instead of Bool.

* Better density function for gamma and Poisson distributions.
* Performance improvements for Mann-Whitney U and Wilcoxon tests.

* Cauchy-Lorentz distrbution is added.
* sortBy is added to S.Function.

* Function S.Function.create is removed. Use generateM from vector
package instead.
* Mean and variance for gamma distribution are fixed.

* Much faster cumulative probablity functions for Poisson and
hypergeometric distributions.

* Better density functions for gamma and Poisson distributions.

* Student-T, Fisher-Snedecor F-distributions and Cauchy-Lorentz
distrbution are added.

* The function S.Function.create is removed. Use generateM from
the vector package instead.

* Function to perform approximate comparion of doubles is added to
S.Function.Comparison

* Regularized incomplete beta function and its inverse are added to
S.Function
