add comment to project-Base

outlines need to have some sort of styling to them, even though I hate them.
v 0.6.4

remove clearfix as a mixing and make into a placeholder class instead.

Separate tables into base HTML table styling and Helper classes for tables.

Separate out variables into variables required for/included with brass-tacks, and variables that should be changed on a per-project basis

removed -moz- prefixes from box-shadow, as the market share for super old firefox is almost nonexistent.

removed -moz- & -webkit- from border-radius mixins.

include new page for brass tacks included variables with documentation.

Finalize documentation and base coding for Tables
