paramfetch fails from Filecoin install

[schomatis]

It fails to find parameters.json (which I guess it's not in the usual place). Also, paramfetch may not even be meant to be run from Filecoin, in which case please close this.

~/go/src/github.com/filecoin-project/go-filecoin/proofs/bin$ ./paramfetch fetch 
parameter manifest './parameters.json' does not exist
nothing to fetch

@sidke Can you take a look and close (with explanation) if not applicable? I'm guessing it was a premature attempt before paramfetch was fully released.

paramfetch must be run with either the --json flag or from a directory containing parameters.json.

go-filecoin developers will typically run the following command from the root of the go-filecoin project:

./proofs/bin/paramfetch --all --json=./proofs/misc/parameters.json
