Converted TagCategory into a special dictionary object using TagTranslationTable.

This dictionary object will have the BMRB database table name as a key, and using the TagObject
class object the elements will store information such as the corresponding variable name, the
corresponding BMRB NMR-STAR tag name, a list of allowable values, the missing flag, and any other
tag specific information corresponding to the key.

The free tagtable data is now being collapsed to remove the lists.

Removed all of the useless specific_setup() methods.

The tensor saveframe has been abstracted to use the new base class methods for reading data.

The tag information data extraction has now been abstracted into the base classes.

The BaseSaveframe.extract_data() and TagCategory.extract_tag_data() has been written to take
advantage of the translation tables to automatically fill all the class instance variables with
the tag data.

Abstracted the Tensor saveframe loop() method and shifted it into the base class.

The tensor data reading is now being performed by read_tagtables().

The Tensor tag category is now complete.

The Tensor_list tag category is now completely being created.

Fixes for the reading of the relaxation data back from the BMRB NMR-STAR file.

Huge redesign and simplification of the BMRB tag category classes.

All of the code for setting up these tag category classes has been shifted to the base class. These
classes now only contain a label, and two translation tables for the BMRB tag names and the class
variable names. This redesign has removed many bugs in the saveframes, including many tag
categories no longer being free.
