Issue 16: moved hardcoded values to configuration file.

Now the hardcoded values used in applyPDRMethod.py can be set
from the configuration file. The default values are the same they used
to be. In particular:

- The error for srho (in pixels) -> srho_error
- sdd0 for values in which sdd0=0 -> sdd0_hardcoded
- rho cut-off -> rho_cutoff
(we may want to make this equal to minDistance)
- UV contrast cut-off -> uvContrast_cutoff
- dd0 cut-off -> dd0_cutoff
