Grid analysis of a non-ED tuning against itself

[j5v]

As a user, I want an analysis of all currently-visible intervals of one selected non-ED tuning, displayed in a new Tunings tab.

Hints

We currently have a hidden tab, and logic to branch out to analysis modes for:

• Analysis of an ED tuning, as a single row or column.
• Tuning 1 vs Tuning 1 analysis in a grid, for a non-ED tuning. <-- this issue
• Tuning 1 vs Tuning 2 analysis in a grid.

This issue implements content for the function analysisSingleTuningTableHTML(), which currently holds placeholder text.

Proposed content

Reuse the layout and cell content from analysisNoteIntervalsHTML(), except using the same tuning on both the horizontal and vertical axis. 'Refectoring for reuse' might be beneficial.
