RoboFont: temporary designspace + designspaceChecker to report on glyph compatibility issues.

prrrrrr.py

"""

    test all open fonts on compatibility
    create temp designspace file
    align all fonts on a temp axis
    order does not matter
    run designspaceProblems
    present the data somehow

Result:
    
comparing:
	 geometryMaster2.ufo
	 geometryMaster1.ufo
	 geometryMaster1_no_kerning.ufo
	 geometryMaster3.ufo
glyphs:
	broken_component
		different components in glyph
		different number of contours in glyph
		incompatible constructions for glyph
	extra.glyph.for.neutral
		default glyph is empty
	glyphFive
		incompatible constructions for glyph
	glyph_with_many_contours
		different anchors in glyph
		different number of contours in glyph
		incompatible constructions for glyph
	narrow.component
		different components in glyph
		incompatible constructions for glyph
