localPath

installing new DyanamoDB does not add the local path in the path.

I have to assign localpath to "bin" in order to install the database.

`[ '-Djava.library.path=/Users/aaalsubaie/Projects/propman-server/node_modules/dynamodb-localhost/dynamodb//bin/DynamoDBLocal_lib',
'-jar',
'DynamoDBLocal.jar',
'-port',
8000 ]`

this might be the source of the problem:
`db_dir = utils.absPath(config.setup.install_path)`

Start by tracing the install path through the `db_dir = utils.absPath(config.setup.install_path)` entry point and compare it with the reported `java.library.path` command. Confirm how the `bin` directory is selected during a new DynamoDB installation. Done means the local library path is added automatically and the database starts without manually assigning `localpath` to `bin`.
