FIX: changes to readDX, fixes issue #4
- fully interpret and return the header information
- read only the amount of data indicated by the header regardless of file size
- remove static truncation to 128 range bins

FIX: changed import datatype in read_radolan_composite to uint16 and added
type cast in order to avoid problems similar to those reading RX-data

MIN: removed rho as argument from process_raw_phidp_vulpiani because it is not used anymore.

FIX: Fixed an error related to the window length in the finite difference scheme of kdp_from_phidp_finitediff.

FIX: Removed several bugs from new function process_raw_phidp_vulpiani in module dp.

REF: A lot of formal changes in the dp module including renaming of functions and an enhancement of process_raw_phidp2.

Providing more informative function names

kdp_from_phidp --> kdp_from_phidp_finitediff

kdp_from_phidp2 --> kdp_from_phidp_linregress...

ENH: Added function aggregate_equidistant_tseries to util module.

This function aggregates time series data under the assumption that the source
and the target time series are equidistant, and that the source time steps
regularly fit into the target time steps (no shifts at the boundaries)....

ENH: Added function timestamp2index, which allows to calculate indices of
an equidistant time series from time information (human readable strings or
python datetime/timedelta objects).
... and helper functions.

MIN: Passing the window size for KDP retrieval consistently as a kwarg in process_raw_phidp2.

MIN: Some minor changes in ErrorMetrics.

Including that (i) pbias is now computed in percent as it should, (ii) pbias
is reported by default, (iii) avoiding reports and plot attempts of no valid
pairs of obs and est are available.

MIN: Removed a minor TODO warning that is always and annoyingly printed to the screen.

MIN: cg_plot.colorbar routine
added check for integer/real numbers for proper display of ticklabels

Merged in kai_muehlbauer/wradlib_miub (pull request #11)

#11: Improvement io.py - read generic hdf5

MIN: one last cleanup.

FIX: made read_RADOLAN_composite return its data properly multiplied by the
precision factor found in the header.
This is a major change in behavior! Even though it may be considered as a
bug fix it will break code for most users who worked with this function...

FIX: made read_RADOLAN_composite close its opened file.
