* added option, --dendrogram, to perform hierarchical clustering on gmtk parameters, the dendrogram for row-wise clustering is shown
* fixed the inconsistency in column labels of gmtk parameters when hierarchical clustering is performed
* automated the adjustment of spacing between dendrogram and gmtk parameters, allowing dendrogram labels to display properly
* eliminated the --normalize-gmtk option by producing two figures (normalized & non-normalized) when --parameters is used, one figure otherwise
* added max-min table under normalized Parameters
* modified png dpi to be 350
