Started porting over Franz's point target analysis tool. Currently it is determining the peak amplitude and the offsets in x and y.

Adapted an extended version of calc_stats that allows to change the reporting level (just calculate and keep quiet about it).
Minor overhaul for the calibration functionality:
- set the ground value to 0.0 for power scale images
- no noise floor removal anymore

Fixed the multilook processing.

Added --dry-run option. Added checks for properly installs asf tools
Forgot to set the correct background value for the asf_calibrate path.
Merge pull request #16 from rudigens/master

One more fix for calibration background value.
Implemented the same higher order interpolation for ALOS Palsar data that is used for ERS precision state vectors.
Merge pull request #17 from rudigens/master

higher order interpolation scheme for ALOS Palsar
Looks like we worked out the radiometry problems. A little bit of
verification and we might be good to go.
Added framework for analysis tool.
Merge branch 'master' of https://github.com/asfadmin/ASF_MapReady
Added mean and standard deviation calculations
updated usage to correspond to actual script name ;)
