Implemented option to hide image when opening

Quick and dirty hack to allow imagej (python) scripts to open hdf5 files via a routine and do operation with them.
This is far from perfect and needs major cleanup! It is implemented like this due to lack of time ...

 ImageJ plugin for reading and writing HDF5 files.

+## Scripting

+To use this plugin from the ImageJs' (python) scripting interface these lines can be used to open a dataset:
+
+```python
+from ch.psi.imagej.hdf5 import HDF5Reader
+reader = HDF5Reader()
+stack = reader.open("",False, "/Users/ebner/Desktop/A8_d_400N030_.h5", "/exchange/data_dark", True)

 # Installation
 To be able to install this plugin ImageJ need to be run with a Java 7 or greater JVM.

 Starting with Java 8 just the LD_LIBRARY_PATH variable need to be set. For MacOSX it is export `DYLD_LIBRARY_PATH=lib/mac64/:$DYLD_LIBRARY_PATH`.
 
 # Development
+
+To be able to run the tests and plugin from within the following arguments need to be passed:
+
+![RunSettings](RunSettings.png)
+
 To create an all in one zip file for installation in a ImageJ installation use: 
 `mvn clean compile assembly:assembly`
 
 The zip file contains an all in one jar as well as the required native libraries for Windows, Linux and Mac OS X.
 
+Note: to be able to build the package you need to have access to the PSI artifact server. Therefore this only works within the PSI networks and if you have a certain maven configuration. An example Maven settings.xml that you can copy to `~/.m2/settings.xml` is located [here](settings.xml).

 # Acknowledgements
 This project was inspired by the ImageJ HDF Plugin of Matthias Schlachter Chair of Pattern Recognition and Image Processing, University of Freiburg, Germany ( https://code.google.com/p/imagej-hdf ) . 
 It is a complete rewrite of the code with the focus on efficiency and maintainability
