Added method convertToOrgLinkNotation that converts from geeknote style
links to org mode style links. And tests
Apparently the org mode doesn't quite export strings so we are dropping
the idea of parsing the markdown generated by org mode.

* Added funtions to go back and forth between evernote/md/geeknote style
  links and org mode links
* Added functions to parse Org mode table into the OrgTable object
* Start of writing the OrgTable to a html table
