This is the main class instantiated by Applications.
- Manages a single WJ Multi-Protocol Reader.
- Provides properties and methods for accessing features of the MPR.
- Talks to the MPR via an MPRComm object.
- Generates request frame payloads for MPR API commands.
- Parses response frame payloads from MPR API commands.
- Fires events when MPR public properties change
- Manages an Inventory of Tags in the MPRs field of view.
- Inventory can consist of Class 0, Class 1 and/or Gen 2 tags.
- Periodically polls the MPR for its current Inventory to:
1) add new tags when found
2) expire old tags
- Old Tags are expired if they have not been seen for at least "PersistTime"
- InventoryUpdateGap is how long to wait between inventory requests to the MPR.
- Has methods to enable bootloading new FW to the MPR.
- Exposes MPR methods to Read/Program/Erase/Kill/Lock for 3 EPC Tag standards.
