Unexpected behavior when working with classifications with > 2 levels

[petebankhead]

Object classifications can form hierarchies in QuPath, as described in the documentation.

A derived class should be shown with a colon separator, e.g. Tumor: Positive and Tumor: Negative are both derived from a base classification of Tumor.

This appears to work fine, but if there are more than two 'levels' to the classification then only the final two are displayed through the user interface. Therefore while Tumor: E-cadherin: Positive can be represented in code, it would only be shown as E-cadherin: Positive on screen.

The following script can be used to print out what all the levels of the classification are.

// Get classification of selected object
def pathClass = getSelectedObject().getPathClass()
println("Classification is " + pathClass)
if (pathClass == null) {
    return
}

// Print the full classification
String fullName = pathClass.getName()
pathClass = pathClass.getParentClass()
while (pathClass != null) {
    fullName = pathClass.getName() + ": " + fullName
    pathClass = pathClass.getParentClass()
}
println("Full classification hierarchy is " + fullName)

Additionally, the Classify by specific feature command does not pay much attention to hierarchies of classification - which is somewhat unintuitive, and requires updating (or replacing).
