Now with merge  order output.
Changed dependency from igraph to igraph0. Vertexes are 1-indexed in igraph and appear to be affecting the web rendering of gml files.
Create populationRules from fcsChannelMapping.
Use third column of rules file to match fcs file columns for cell probability calculation
Create merge order files per cell type
Added untransformed medians and folds to gml file.
Replace spaces with underscores for merge order files
Use node 'name' instead of 'id' during merge order file creation.
Merge branch 'cytobank_release' of github.com:nolanlab/spade into cytobank_release
Revert back to using 'id' field of node instead of 'name' for merge order. Spade rendering code in cytobank references nodes by id
