Version 0.6

Changes

Prettier output for equalMeans function.

Fixed a bug when variances where constrained to be positive in a model
with group comparisons and no mean structures: In this case, only the
variances of the first group were constrained. Now it's fixed: both
groups are constrained.

Added new data sets: clinical, clinical.wide, two.groups,
two.groups.wide

When running a two-group analysis, plots automatically show both groups

Fixed a bug where the ordering of labels in the meanstructure-plot was
wrong
