This class is used to represent the textlabel object in C from the Graphviz library
Objects can be created by calls of the form new("AgTextLabel", ...).
labelText:Object of class "character" The
actual label text
labelLoc:Object of class "xyPoint" The
location of the label
labelJust:Object of class "character" The
justification of the label
labelWidth:Object of class "integer" The width
of the label
labelColor:Object of class "character" The
color to print the label
labelFontsize:Object of class "numeric" The
font size for the label
Retrieves the labelText slot
Retrieves the labelLoc slot
Retrieves the labelJust slot
Retrieves the labelWidth slot
Retrieves the labelColor slot
Retrieves the labelFontsize slot
