Folder navigator

[tolstenko]

Create the data structure and/or database(sqllite?) to navigate recursively through all dicom files from a folder and map for each patient. Here are some tags I found google "gdcm dicom tags" for more tags:

• (0010,0020) ?? # 4,1 Patient ID - the patient identification
• (0010,0010) Patient name
• (0020,0010) ?? # 2,1 Study ID - the grouping reference that unites all series that happened in the exam acquisition.
• (0008,1030) Usually, the studies description are named by something queriable
• (0020,0011) ?? # 2,1 Series Number - the grouping identification of all image set that composes a voxel volume. usually, it is named the same name as the contrast phase: ex. arterial, portal...
• (0020,0013) ?? # 2,1 Instance Number - the slice id of the voxel. It is like the orthogonal cut of the voxel volume

Once the data is loaded into the database, you can present and enumerate all possible studies in a hierarchical similar fashion to finder does on mac: https://i.stack.imgur.com/GiecU.jpg or in any other meaningful way.

In order to compose a voxel volume to be rendered, it is relevant to know the thickness too. (0018,0050)

@dillondrum70 I created a bunch of useful functions here https://github.com/InfiniBrains/DicomViewer/blob/FolderNavigator/voxelvolume.h and dere https://github.com/InfiniBrains/DicomViewer/blob/FolderNavigator/navigatorsystem.h

Now it needs to be connected to the UI.
