Improvement: Proposed name change of FTF -> GBTS seeding

[Rosie-Hasan]

Change naming of new seeding algorithm from FTF (FastTrackFinder) to GBTS (Graph Based Track Seeding) as this is a clearer desription of the algorithm.
Code implemented in PRs #2227 #2726 and more details given presented at ACTS-ITK presention .

The proposed name changes for file names and classes are listed below. I would apprecaite any opinions or feedback on these before the 20th of December, when I will submit a PR of these changes.

• SeedFinderFTF -> GBTSSeedFinder (or SeedFinderGBTS?)
• GNN_DataStorage -> GBTSDataStorage
• GNN_Geometry -> GBTSGeometry
• SeedingFTFAlgorithm -> GBTSSeedingAlgorithm (or SeedingGBTSAlgorithm?)
• FasTrackConnector-> GBTSConnector
• TrigBase -> GBTSBase
• full_chain_itk_FTF.py -> full_chain_itk_GBTS.py

My only request is to write Gbts instead of GBTS in class names, i.e. GbtsConnector.

Comments from my side:

• I Agree with @paulgessinger GBTS -> Gbts
• I'd follow the pattern (for this and any seeding algorithm) for the seeding alg name: <TYPE>SeedingAlgorithm. So I have a preference indeed for GbtsSeedingAlgorithm
• For the seed finder I see other implementations adopt the convention (opposite to the algorithm convention ... maybe in the future we may impose a common pattern for all the Acts Code but not immediately): SeedFinder<TYPE>
• Avoid _ in classes names

Thank you both, I have made the name changes based on these suggestions and will submit a PR soon
