some methods for consideration

• versions YAML for multiqc, some examples here;
  • https://github.com/nf-core/rnaseq/blob/1817d14a3a3a7d130b1fd729c5c3f9a6547b4fd5/subworkflows/nf-core/utils_nfcore_pipeline/main.nf
  • https://github.com/stevekm/dumpSoftwareVersions
• email template
• saving params and other meta JSON's

[stevekm]

consider use of the new~ish "topic" channels and version output channels from Nextflow processes so we dont need to actually create a YAML in every process ; the methods in the plugin should be designed to use those as well
