public class MappedShapeSymbol extends ShapeSymbol
This is a symbol that holds a list of ShapeMap-s. It allows us to map a string pattern to a particular shape type. For example, if a point obs has a filed: aircraft_type which can contain the values:
 military
 glider
 civilian
 ...
This symbol could hold the shape maps: 
 military -> triangle
 glider -> circle
 civilian->square
 ...
