Bugfixes plus Linear Mixed Effects models

Minor bugfixes in the main Bayes factor package
Several additions to the included linear mixed effects model package (+lm), including mediation analysis, between subjects power analysis.

Full Changelog: v2.2.0...v2.3.0

ttest updates

Fixed a bug in ttest and ttest2 for the computation of BF from a T statistic.
This now requires inputting the N.

v2.1.1

Fixes a bug that prevented calculation of Rouder's S in recent Matlab versions (due to parfor)

v2.1.0 - Adding log numerics and linear model analyses

Added the option to compute with log(probabilities) - necessary for large data sets where the product of many probabilities is too small compared to machine precsision. See internal.ral and bf.anova and use bf.options to enable this for your computations.

Added utilities in the +lm package to work with linear models directly (and compare with Bayes factor approaches).

v2.0 - beta

Initial beta release. Working code, added documentaiton, tested against published numbers and R package.
