Create INSPQ-TOPO.csl

New Style.
I try to avoid ```<text value``` as much as possible. Instead, use 
```<text variable="DOI" prefix="http://dx.doi.org/"/>```
On a sidenote, the dx isn't necessary anymore and in fact doi.org is now the preferred resolver, so I'd recommend going with ```prefix="http://doi.org"``` but that's up to you.
