Initial commit of concepts page for Composition of Observables-Indicators
Initial commit
Merge branch 'master' into composition
Added set of examples
Added a table of suggested practice content for composition
Standardize whitespace and move to two-space indention in XML samples.
Change default link text for collapsible sections.
Add button to expand all examples
Implement toggleable links that will switch between an 'enabled' and 'disabled' state via different text displays. Update some class declarations, as using 'collapse' makes uncollapsing impossible (Bootstrap's collapse function changes this class based on state.)
Use built in bootstrap event firing and simpler jquery to correctly collapse and expand all items.
Changed title for page and restructured with simple overview content for each area with hide/show links to provide the more detailed content.
Restructured content with simple overview write-ups and hide/show links to the more detailed content and examples.
