Added Toro1997 attenuation model

[navarroc]

I've added the Toro 1997 attenuation model from Ergo. To test this out, do the following steps:

To create an example earthquake using Toro1997 on your local machine, use the following JSON:

{
   "name":"Memphis toro EQ Model",
   "description":"Memphis model based hazard",
   "eqType":"model",
   "attenuations":{
      "Toro1997":"1.0"
   },
   "eqParameters":{
      "srcLatitude":"35.927",
      "srcLongitude":"-89.919",
      "magnitude":"7.9",
      "depth":"10.0"
   },
   "visualizationParameters":{
      "demandType":"PGA",
      "demandUnits":"g",
      "minX":"-90.3099",
      "minY":"34.9942",
      "maxX":"-89.6231",
      "maxY":"35.4129",
      "numPoints":"1025",
      "amplifyHazard":"true"
   }
}

To test your newly created earthquake, use the following, replacing {id} with the ID of the EQ you created:

POST http://localhost:8080/hazard/api/earthquakes/{id}/values
JSON body is:

[{"demands": ["PGA"],"units": ["g"],"loc": "35.1373, -89.99892"}, {"demands": ["0.2 Sa"],"units": ["g"],"loc": "35.13916, -89.9914"}]

For the provided attenuation and locations, the values returned from the local service should be:

[
   {
      "hazardValues":[
         0.28649803773513977
      ],
      "demands":[
         "PGA"
      ],
      "units":[
         "g"
      ],
      "loc":"35.1373, -89.99892"
   },
   {
      "hazardValues":[
         0.6157173468407837
      ],
      "demands":[
         "0.2 Sa"
      ],
      "units":[
         "g"
      ],
      "loc":"35.13916, -89.9914"
   }
]

I posted the earthquake and tried to get values. Both methods worked as they were written in test description.

maybe you can remove this double m =
