Implemented rmsd calculation (based on Jama matrix package)
rmsd method still not taking care of unobserved or missing atoms. Also not returning individual distances between optimally superimposed structures (although it can calculate them in commented out code)

Made ContactList a TreeSet instead of an ArrayList, should improve performance (log(n) rather than linear)
REFACTORING: 
ContactList -> EdgeSet
Contact -> Edge

Added method getCopy

Now checking in addEdge that we don't duplicate edges
New methods: get2ndshell, copyKeepingNodes

added class NodeSet

Now calculate_dist_matrix returns the matrix with residue serials as indices (rather than atom serials)
Now AA.isValidSingleCT and AA.isValidMultiCT check also for crossed cases

Now can do crossed contacts also with geometric hashing
Renamed getGraphGeometricHashing to get_graph (so interface remains as it was before we introduced the geometric hashing)

First geometric hashing implementation for calculating graph (with new class Box). Only does non-crossed cts
Geometrich hashing graph calculation kept in a separate method than normal get_graph. Still either of the methods can be used.
Using javax.vectormath objects for the vectors (distance method also from that)
Using TreeMap for get_coords_for_ct

Now calculate distance matrix uses HashMap instead of TreeMap
Needed to change the hashCode function in Contact to make it faster

Added cross contacts to isValidCT

New secstruct2resinterval TreeMap to store secondary structure elements as a map of ss string ids to intervals
New class Interval

Now reading also secondary structure (in a map of residue serials to secondary structure identifiers)

now casting pdb codes to lower and pdb chain codes to upper in all constructors

Fixed bug: ATOM lines printing was locale dependant, thus was printing ',' for decimal separators in some locales

some clean up of exceptions in Pdb and Graph classes:
merged PdbAcCodeNotFoundError and MsdAcCodeNotFoundError into PdbCodeNotFoundError,
created new PdbChainCodeNotFound, got rid of stderr output, throwing exceptions with informative messages instead

Fixed bug in regex introduced in last revision

Fixed graph file format checking, was not working properly

Now throwing also SQLExceptions for individual queries, not just for connections

Throwing exception also in case graph file not in right format at all (no #AGLAPPE in 1st line)
Fixed bug: was not reading correctly #PDB CHAIN CODE

FIXED BUGS:
- directed was not set when reading from cm file
- pdbChainCode not set when reading from db given pdbCode
- filling pdbresser2resser and resser2pdbresser hashmaps also in reading from pdb file
- using "A" as chainCode when reading from pdb file
- some error handling for file formats: new exception classes GraphFileFormatError and PdbfileFormatError

Restructured construction of Pdb and Graph objects: now subclasses for each case
Cleaned up and made consistent database connections
Now can also pass a MySQLConnection in all cases (as well as having default values for a default connection)
PdbaseInfo and MsdsdInfo classes removed: now merged into PdbasePdb and MsdsdPdb respectively
Updated following this changes testPdb and compareCMs

Major refactoring:
 accode -> pdbCode
 chaincode -> pdbChainCode
 chain -> chainCode
Major change of signatures (publics to privates)
Implemented getters for needed member variables
Major clean up

Using apache xmlrpc version 3.0 in PyMolServerOutputStream

MySQLConnection now throwing SQLException on connect
Many files changed following this: all calling classes now re-throwing or catching the SQLException

Implemented hashCode method in Contact and GenericContact. Was necessary to use these classes as keys in Maps
Fixed bug in equals method in GenericContact
Changed middle character from "\t" to " " in toString

New class GenericContact. To store a generic contact, i.e. a pair of residue types

Fixed bug: calculateEntropy was wrong when a pi was 0

FIXED BUG: the switch statement was missing the breaks
This was causing strange behaviour in counts NodeBackground getSize methods and also was making them being too slow

New class NbhProbDistribution
In NodeNbh implemented a few static classes to convert between different motifs and to match motifs using differing criteria

FIXED BUG: fixed restrictContactsToMax/MinRange. Couldn't delete contacts at the same time as looping in them
NEW CLASSES NodeNbh and EdgeNbh, now used in getNodeNbh and getEdgeNbh
New method getResidueType

Fixed bug in getMaxRange method, was not assigning to the max variable
Added toString method to Contact

FIXED BUG in initialisation of fullLength when reading from file. In case of no sequence and nodes provided, was not getting correctly the maximum value for contacts. Now using the method getMaxContact from new class ContactList
NEW FUNCTIONALITY in Graph:
-New member variable modified
-New methods addEdge, delEdge, restrictContactsToMaxRange, restrictContactsToMinRange, getContacts, getNodes, copy
-Improved slightly the implementation of getEdgeNbh
