* "execute" is meant to send the command to the engine

* (i.e. look at the next entity for getActionInfo, the next
* possible action for the actionCheck ...)
* They will return an object when the searching is finished
*
* "getActionInfo" is used to determine if the action is possible,
* and also give visual feedback to the user (tooltips, cursors, ...)
*
* "preSelectedActionCheck" is used to select actions when the gui buttons
* were used to set them, but still require a target (like the guard button)
*
* "hotkeyActionCheck" is used to check the possibility of actions when
* a hotkey is pressed
*
* "actionCheck" is used to check the possibilty of actions without specific
* command. For that, the specificness variable is used
*
* "specificness" is used to determine how specific an action is,
* The lower the number, the more specific an action is, and the bigger
* the chance of selecting that action when multiple actions are possible

// towers in the case of snapping). The towers themselves all keep their default unique control groups.
// To support this, every non-tower piece registers the entity ID of the towers (or foundations thereof) that neighbour
// it on either side. Specifically, each non-tower wall piece has its primary control group set equal to that of the
// first tower encountered towards the starting side of the wall, and its secondary control group set equal to that of
// the first tower encountered towards the ending side of the wall (if any).

// - Go from start to end and construct wall piece foundations as far as we can without running into a piece that
// cannot be built (e.g. because it is obstructed). At each non-tower, set the most recently built tower's ID
// as the primary control group, thus allowing it to be built overlapping the previous piece.
// - If we encounter a new tower along the way (which will gain its own control group), do the following:
// o First build it using temporarily the same control group of the previous (non-tower) piece
// o Set the previous piece's secondary control group to the tower's entity ID
// o Restore the primary control group of the constructed tower back its original (unique) value.
// The temporary control group is necessary to allow the newer tower with its unique control group ID to be able
// to be placed while overlapping the previous piece.
//
// SECOND PASS:
// - Go end to start from the last successfully placed wall piece (which might be a tower we backtracked to), this
// time registering the right neighbouring tower in each non-tower piece.
// first pass; L -> R
