Consolidate accuracy 2

[RobinL]

Supersedes #2147

Consolidates

truth_space_table_from_labels_{type}
roc_chart_from_labels_{type}
precision_recall_chart_from_labels_{type}
accuracy_chart_from_labels_{type}
threshold_selection_tool_from_labels_{type}

to

accuracy_analysis_from_labels_{type}

Where {type} is either 'table' or 'column

Questions:

• Should truth_space_table_from_labels_ be a separate function, since its return type is different?
• Should we bother retaining the precision_recall and roc options?

Closes #2010
