A mongo db migration tool written in native javascipt.
Mongoose works by executing the mongo scripts from the folder migrations. The scripts named as:
    execute-order_migration-name.js
    eg: 0001_my_first_migration.js
The migrations are executed sorted in the order using the execution order. Once a script is executed, mongoose keeps a tack and dowsnot execute it in case Mongoose is run again. In order to do so, it keeps track of the migration file name.
- 
cd into the mongoose directory.
 - 
run the mongoose.js on mongo console as:
mongo <dbname> -u <username> -p <password> --host <host name> --port <port number> mongoose.js
