Installation is broken

To install TempoSimple, you simply need to get the source and download the dependencies:

    git clone https://github.com/gnugat/tempo-simple.git
    cd tempo-simple
    git checkout -t origin/fix/install
    composer install

You need then to create the database:

    php app/console doctrine:database:create
    php app/console schema

Problem is: when launching the console, the following error occurs:

    [PDOException]                                     
    SQLSTATE[42000] [1049] Unknown database 'xxx'

This means that currently the user has to manually create the database and schema :/ .
