Usage: `loads a block test file`,

Description: `
|
|
The first argument should be a block test file.
|
|
The second argument is the name of a block test from the file.
|
|
|
|
The block test will be loaded into an in-memory database.
|
|
If loading succeeds, the RPC server is started. Clients will
|
|
be able to interact with the chain defined by the test.
