 The model aims to be a generic model for phenology prediction of a number of species of plants and insects. It is based on the assumption that the development of the specimen is temperature driven. Its general nature requires the user to provide both weather data and the specific characteristics data for the species/variant at hand.

+Please observe these properties:
+* speciesLatinName: Should be (but isn't in the example!) the latin name of the species
+* typeName: If we have a variant of the species (typically for plants), write the name here
+* algorithmId: Defining how we calculate the day degrees. 
+    1. Basic day degree model with mean temperature and base temperature
+	2. Daily heat sum calculated from hourly values based on base temp, max temp, opt temp (TODO: Document the model)
+* baseTemp: For the day degree calculation (at least methods 1 and 2)
+* upperTemp: For the day degree calculation (at least method 2)
+* optTemp: For the day degree calculation (at least method 2)
+* startDate: The date (as a Unix timestamp) for when the calculation starts. Also known as biofix
+* weatherParams: Array of weather parameters needed for the calculation. TM = Mean temperature
+* plantations: Array of development phases of the species, in the correct order
+* observations: Array of weather observations
