This is the first step to introduce a configuration file for abra. The config file must be named `abra.yaml` or àbra.yml`. abra look for the config file in the current directory and when not found traverses the directory tree up until it is found or the home/root directory is reached.
For now there is only one setting that is made configurable: `abraDir`. The new logic for setting the abra dir is the following:
1. lookup `$ABRA_DIR` env
2. look for config file and take value from there
3. `$HOME/.abra` as fallback
