Merge pull request #247 from enthought/feature-repeater

Feature repeater
Refactor the compiler to generate description dicts.

This update allows the creation of templated types which delay the
creation of objects until runtime. Based on this ability, Looper
has been refactored to create an independent scope for each loop
iteration, and a Conditional component has been written.
Add some somewhat decent error reporting when global lookups fail.
Cleanup documentation and remove dead code.
Update line numbers in documentation
Update exception handling.
