Normalize coverage
Unit tests for normalization methods
Args.txt files updated to work with new normalize argument
normalize by samples first and contigs second
added nose temp output directory to gitignore
Normalize per sample as well, plus made normalization into methods
Merged upstream changes
if normalize parameter specified we normalize coverage before we log transform (log transform is always done)
Added travis build button

Show build status of master branch
Merge branch 'master' of github.com:BinPro/CONCOCT
Made normalizing coverage default. Updated tests and reference result files to reflect that.
Merge branch 'master' into normalize_coverage
renamed the normalize flag
Now testcases both for normalizing coverage and for no normalization of coverage
Changed axes labels in ClusterPlot.R
Added a test I previously modified to represent normalization (so now we test log coverage value for both normalized and no normalization of coverage). Removed redundant test of normalization of coverage
Merge branch 'master' of github.com:BinPro/CONCOCT
Adapted tests to new no_total_coverage parameter
Added total coverage column to coverage by default
Moved main script from package to bin directory
