Fixed wasAssociatedWith edge orientation in input.xml
Removed old comments
Corrected Temporal_Layout to be compatible with the new orientation
Updated BaseFatos to be in accordance with the new input.xml (with the edge changes)
Updated BaseFatos to include new prolog rules: 
	-Compute Standard Deviation of a list,
	-Create a list of attributes values to compute the standart deviation, 
	-Sum of a List, 
	-Square List, 
	-Variance of a List, 
	-Paths restricted by Type of edge (allowing vertical or horizontal collapses depending on the edge used),
	-Add element to a list
	-Threshold check for the difference of two values ( abs(X - Y) < threshold ), used in CollapseFilter
	-CollapseFilter, which collapses nearby vertices (shares a path) in which the difference of values is lower than the standard deviation for the type of the Attribute that is being evaluated. Returns lists (of lists) of vertices that need to be grouped together.

TODO: Incorporate prolog queries in Prov Viewer to auto-collapse when changing display views according to the list of vertices from prolog's CollapseFilter (Using JPL)
