Removed completed tasks section, restored future tasks, added conf intervals.

<li>Framework and implementation strategie(s) for finding roots or real-valued functions of one (real) variable. Implemented algorithms: Brent-Dekker, secant, simple bisection.</li>
<li>Cubic spline interpolation.</li>
<li>Bivariate Regression, correlation. </li>
<li>Sampling from Collections</li>
<li>Add higher order moments to Univariate implementations.</li>
<li>Binomial coefficients -- incorporate an "exact" implementation that is limited to what can be stored in a long. Also provided double-value implementation of binomial coefficients and their logs.</li>
<li>Add percentiles to stored Univariate implementations</li>
<li>Improve numerical accuracy of Univariate and BivariateRegression statistical computations</li>
<li>t-test statistic needs to be added and we should probably add the capability of actually performing t- and chi-square tests at fixed significance levels (.1, .05, .01, .001).</li>
<li>numerical approximation of the t- and chi-square distributions to enable user-supplied significance levels.</li>
<li>The RealMatrixImpl class is missing some key method implementations. The critical thing is solution of linear systems. We need to implement a numerically sound solution algorithm. This will enable inverse() and also support general linear regression.</li>
<li>Added double[] |-> double methods in StatUtils to take start indexes and length as parameters and delegate the current "full array" versions to these.</li>
