update rootlogon.C

update rootlogon.C to include the new storageFormats directory.
storageFormats: fix ampTreeLeaf usage

Fix amplitudeTreeLeaf usage in the amplitudeFileWriter. Leafnames cannot
contain "[", "]" or "-" signs, so all leaf names are now set by the
amplitudeMetadata constant "amplitudeLeafName", which is set to "amplitude" for
now. Also removed the preprocessor tokens USE_STD_COMPLEX_TREE_LEAFS which
should have been taken out in a much earlier commit.
pyInterface: support loading/saving of fileManager to hard drive

create functions to save/load a fileManager object to/from the hard drive.
These functions are located in pyInterface/package/_fileManager.py and are
executed by calling pyRootPwa.core.saveFileManager (or load). Create a new
script that creates a fileManager and saves it to the hard drive for later use.
The metadata eventsType enum has to be internally handled by a python class
that resembles an enum to allow pickle to save it to the hard drive (bug in
boost::python).
Change the fileManager so that it takes a config object to initialize instead
of a config filename (config object is initialized in the outer scripts).
Remove the initialization of the particleDataTable (should also happen in outer
scripts). Do not calculate the amplitude file names with a function call each
time you need them, but calculate them once upon initialization and save them
to a list.
pyInterface: add userInterface/calcAmplitudes.py script

add a high level script that takes a config file and calculates all amplitude
files that the fileManager (which should be created by using the
createFileManager) knows.
Remove initialization of particleDataTable in package/amplitude.py, this should
only happen in the outer level scripts.
