Add Mayfly emergence map

[TheCodeSharman]

As a Mayfly Muster user I want to be able to open a map view which shows a coloured dot for each of the following families:

Siphlonuridae QE01 Baetidae QE02 Oniscigastridae QE03 Ameletopsidae QE04 Coloburiscidae QE05 Leptophlebiidae QE06 Caenidae QE08 Prosopistomatidae QE09

• [x] Add map layers for Tasmanian creatures
• [x] Split layer into a diffrent coloured dot per species above
• [x] Display a legend that is expandable and listed species
• [x] Make each species link to the appropriate taxon node
• [ ] Add emergence information in taxon node screen
• [ ] Add emergence information on legend in map screen (??)

Example mockup of emergence data:

| J |  F |  M | A | M | J | J | A | S | O | N | D |
|                   <------------------->         |

Given: I'm at the Emergence Map screen When: I select the open the legend Icon Then: A legend displaying the family name along with emergenace months is displayed When: I select a family Then: The taxon screen is opened And: The emergence data is displayed along with the rest of the taxon details

@flatworm You'll need to add the folowing field to each of the taxon nodes the taxa.hydro.ink file: emergence: { "startDate": "dd/MMM", "endDate": "dd/MMM" }

We decided to postpone the completion of this: the current state meets the hydro contract requirements - and until we have more data about emergence this isn't high priotity.
