* New last/dotplot module for pairwise similarity plots The `last-dotplot` tool takes a pairwise alignment in [MAF](http://genome.ucsc.edu/FAQ/FAQformat.html#format5) format, possibly compressed with gzip, or in a tabular format produced by the `maf-convert` tool, and produces a similarity dot-plot of the two sequences in one of the graphical formats supported by the Python Imaging Library. A the tool guesses the output format by the file extension of the file, which is constructed by the module at run time, I have used the `args2` option to convey this information to the module. This new module is part of the work described in Issue #464. During this development, we fix the version of LAST to 1219 to ensure consistency (hence please ignore lint's version warning). * Update the functions.nf file to the dev branch. https://raw.githubusercontent.com/nf-core/tools/dev/nf_core/module-template/software/functions.nf
