/* Return an integer that corresponds to what kind of tap dance should be executed.
*
* How to figure out tap dance state: interrupted and pressed.
*
* Interrupted: If the state of a dance dance is "interrupted", that means that another key has been hit
* under the tapping term. This is typically indicitive that you are trying to "tap" the key.
*
* Pressed: Whether or not the key is still being pressed. If this value is true, that means the tapping term
* has ended, but the key is still being pressed down. This generally means the key is being "held".
*
* One thing that is currenlty not possible with qmk software in regards to tap dance is to mimic the "permissive hold"
* feature. In general, advanced tap dances do not work well if they are used with commonly typed letters.
* For example "A". Tap dances are best used on non-letter keys that are not hit while typing letters.
*
* Good places to put an advanced tap dance:
* z,q,x,j,k,v,b, any function key, home/end, comma, semi-colon
*
* Criteria for "good placement" of a tap dance key:
* Not a key that is hit frequently in a sentence
* Not a key that is used frequently to double tap, for example 'tab' is often double tapped in a terminal, or
* in a web form. So 'tab' would be a poor choice for a tap dance.
* Letters used in common words as a double. For example 'p' in 'pepper'. If a tap dance function existed on the
* letter 'p', the word 'pepper' would be quite frustating to type.
*
* For the third point, there does exist the 'DOUBLE_SINGLE_TAP', however this is not fully tested
*
