- refactored some code to do with how contacts are imported
- Vcards (and ContactData) instances now generate a CacheIdentifier when they are finalised so that ContactData instances that do not have enough information to identify them can be discovered then
- importContact() now calls the private method checkForDuplicate(), renamed from isImportRequired(), and return if it is not
- importContact() and checkForDuplicate() now use the ContactData's generated CacheIdentifier
- Vcards (and ContactData) instances now generate a CacheIdentifier when they are finalised so that ContactData instances that do not have enough information to identify them can be discovered then
- importContact() now calls the private method checkForDuplicate(), renamed from isImportRequired(), and return if it is not
- importContact() and checkForDuplicate() now use the ContactData's generated CacheIdentifier
- files renamed:
- src/org/waxworlds/edam/importcontacts/VCFImporter.java => src/org/waxworlds/edam/importcontacts/VcardImporter.java
