Glridb 315 integrate catchments into portal

I'm seeing a lot of repetition:
```
CONFIG.prop1.propA.propDelta='value'
CONFIG.prop1.propA.propBeta='value2'
CONFIG.prop1.propA.propPhi='value3'
```
The code would be more declarative and less repetitive if as many assignments as possible were done on CONFIG's instantiation using object literal syntax:
```
var CONFIG = {
    prop1: {
         propA:{
                propDelta: 'value',
                propBeta: 'value2',
                propPhi: 'value3'
          }
    }
}
```
