Alan Mishchenko 22406e7101 Merged in boschmitt/abc (pull request #28) 
Handling D1C and SCC in FXCH
 2016-06-17 21:53:04 -07:00
Alan Mishchenko c912875261 New command 'phase_map'. 2016-06-17 20:21:39 -07:00
Bruno Schmitt 85428a60cc Enables FXCH to handle Distance-1 cubes (D1C) and Single Cube Containment (SCC) as by product of extraction. 
D1C: Whenever they appear a constant divisor (x! + x)  will be created and handle as any other divisor.
SCC: Will be taken care of as soon as they appear.
