Experiment with a git repo as data storage.

Going another route, cannot make git commands work in python for now.
Implementing new database construct.

New database construct will have a network location and a local database.
The program can run without network connection, but it must have an
initial database.
Inserted method to have a local and network DB

Inserted and tested (manually) methods to check for the existence of local
and network databases and copy them over if needed. Requires further
testing.
Finish db copy method, start of import method

Finished the db copy method, so the program database is now properly
copied over if nessesary from and to the network storage. Uncoupled the
program database and the tidal data databases.
Import method for access database in progress.
bugsquash for no GNA network connection
Added loading tidal data into numpy arrays

in progress, needs some work.
merge conflict, using newly created file
New database protocol implemented.

Database is now devided between a 'program' database and (several) 'tidal'
databases.
Integration of numpy arrays for tidal data storage and calculations.
