Data model documentation refinements

[Bankso]

Following #49, #66 and in addition to #67

Initial deployment here: https://mc2-center.github.io/data-models/

Ideas for changes/additions to the data model documentation (in no particular order):

1. for any component or valid value table, include the type and description alongside the table name.
   • General form example:
     • type: name
       • description
   • Specific example:
     • Attribute: Dataset Assay
       • the experimental assay associated with the content in the dataset
2. add a template/model table that shows the component/data type, description of the component, and link to the component attribute table
3. in attribute tables, add a link to the valid values associated with each attribute
4. show the template/component directory on the home page and move the term dictionary to the second header tab
5. modify the term dictionary to display the following:
   • Components (or Data Types, Data Models?) --> link to table listing all components
     • list component names and links to attribute tables
   • Attributes --> link to table listing all attributes
     • list attribute names, which link to row in attribute table
   • Valid Values --> link to tables listing all valid values by type
     • list valid value types in alphabetical order, linking to table associated with type
