--lets one construct simultaneously on z-axis
--[[TODO list:
    Add checking for minimap being present when rendering

    Construct # previous buildings (optionally #a to #b previous buildings or selected building(s))
    Allow constructing constructmultiz buildings by simply copying job_filter.

    Construct in x, y or fii° direction. Allow cursor position to determine fii° (useful when combined with previous one)
    This means way to place cursor. mouse_x,_y will work - on same z-level. Burrow named 'cursor' would work on different z-level.
    With lineiterator already present, could theoretically use paintstring to paint the expected line.

    Construct on designations of given type, priority and marked/not /construct on adjacent matching designations.  

    Construct all buildings in a burrow.

    Given a set of buildings and set of locations, loop through the buildings when copying.

    High priority corners

    trigger designation seek when placing on a designation

    Better automaterial support: Keeping constructmultiz settings and automaterial's both visible by masking with display and listening to relevant keys

constructonmultiplezlevels
==========================
    version 1.33
Script to construct multiple z-levels of buildings at once.
Currently uses general seeking for matching material and type,
expect for bucket, barrel, chain, mechanism, screw, pipe, anvil.
General: Dwarf will use the matching item closest to them.

Usage:
  constructmultiz x y
    orders x above and y below same buildings as the last one.
  constructmultiz display
    Displays an indicator_screen in bottom-right for bound x and y
    Also enables Ctrl+A and Ctrl+B to place bindings
  constructmultiz bind
    Adds keybinds to call this when building and exits
  constructmultiz unbind
    Removes keybinds to call this when building and exits
  constructmultiz bindings
    displays list of what bindings it would use and exits]===]
