Shifted the __all__ list from '__init__.py' to 'main.py'.

This is in preparation for the replacement of the current '__init__.py' with 'main.py'.

Bug fix.

The relax data storage object was not accessible by the reset() user function.

Removal of the assignment of Data() to 'self.relax.data'.

The reset() user function has been modified to handle the new data object.

Rather than using the statement 'self.relax.data = Data()', which with the singleton design will
alias 'self.relax.data' back to the data object, a new method 'self.__reset__()' of the data object
is called. This method first deletes the items of the object's __dict__ dictionary key by key and
then reruns the object's __init__() method.

Complete elimination of the references to 'self.relax.data'.

All of relax now handles the singleton design pattern of the relax data storage object, referencing
the global 'relax_data_store' which is set to the reference of the single Data() instance.

major overhaul, explicit running of individual tests now work

Updated many modules to use the new singleton pattern of the 'data.Data' class.

Added an import statement to the 'data/__init__.py' file to simplify the module.

The class Data() can now be accessed by typing 'from data import Data' rather than
'from data.main import Data'. This will simplify the usage of this module for the data model
redesign and allow file names in 'data/' to be changed without affecting the operation of the rest
of relax.

Converted the Data() class from the 'data' directory into a singleton.

For more infomation about this usage of the singleton design pattern, see my post at
