Create the MIxS-HCR project page

[Chris Hunter]

Aim
To create the MIxS for hydrocarbon resources (MIxS-HCR) project page in the new website. The page is currently on the GSC website here:
http://gensc.org/projects/mixs-hcr-gsc-project/

The content of that needs converting to MD and uploading to this GitHub repo as "mixs-hcr-project.md" here: https://github.com/GenomicsStandardsConsortium/gensc.github.io/tree/master/pages/projects/

For a guide on creating markdown files from html see readme.md

The structure of all projects pages is very simple and shouldn't require any additional images or files, but if they do:
Any images used need to be saved here https://github.com/GenomicsStandardsConsortium/gensc.github.io/tree/master/images/
NB- sponsors images may already exist if used in other pages already.

Any additional files e.g. PDF version of agenda or schedule, powerpoint slides etc. need to be saved here:
https://github.com/GenomicsStandardsConsortium/gensc.github.io/tree/master/other-media/
NB- Be aware of the need for unique file names here, e.g. "agenda.pdf" is not likely to be unique! consider adding a prefix of the project-name to all files to be associated with this meeting page.
