Begin refactoring pybom to use a better interface

- Added generic BOMMatcher with Octopart implementation
- Moved caching to a higher layer
- Made the interface compatible with typedargs

Update typedargs with class containing type_system code

- Also expand unit test coverage of type system
- Add default string formatting for exceptions

Update for more consistent use of new type_system

Add initial support for complex types

- Add a map type that can take any two other types as key and value types

Add typed return values to type system

Update bom_matcher to use typed return value

Update typedargs to export return_type

Update typesystem to allow complex types in param and return_type

Fix return value printing

Begin creating provider-agnostic part information

Add list complex type to typedargs

Finish refactoring octopart code
- Start refactoring board extraction and pricing code

Refactored pybom
- Added momo friendly CircuitBoard object
- Simplified generation of pricing models
- Consolidated code for getting bom information

rename bom_lines() to capture what it does

Fix improper location of config file

Start finishign up pcbtool

Fix help display in momo tool.

Remove dirspec dependency and replace with in-house alternative

Update README to remove mention of dirspec

Update typedargs with class containing type_system code

- Also expand unit test coverage of type system
- Add default string formatting for exceptions

Fix improper location of config file

Update for more consistent use of new type_system

Add initial support for complex types

- Add a map type that can take any two other types as key and value types

Update typedargs to export return_type

Update typesystem to allow complex types in param and return_type

Fix help display in momo tool.

Add bool type

Don't require a variant when there is only one option

Add test for circuitboard

- start work on partcache, moving from ZODB to integrated sqlite

Recreate cache functionality on top of sqlite

Still need to integrate into bommatching

Start making CircuitBoard agnostic of the generating program.

Begin the great refactor to make CircuitBoard agnostic of the
type of board file that it was generated from.  This does not
work yet but is on its way.

Rename pybom to pcb

Working version of refactored CircuitBoard

Attribute updating works now on eagle board files

Integrate part cache into bom matching object

Working version of part caching

Working partcache integrated into bom_matcher

Working part caching and unit tests for part matching

Rename unit tests from pybom to pcb to match new package name

Update TODO status

Add support for updating metadata in boards and writing BOM lines

Fix unit tests and partcache to use global defaults

Fix unit tests for pcb tools

Fix refactor copy/paste error and remove unnecessary setup dependencies

Working excel exporting of BOMs

Pump version 1.1.0 since we added a new bom feature

Add unit test to exercise excel exporting

Fix bug handling empty manufacturers

Fix processing of assembly variants in eagle and add tests for it

Update CircuitBoard to support pricing BOMs

- Also fix issue with unicode display inside physical parts objects
not being converted correctly to ascii when using __str__
- Updated type system to include price objects.

Update momo to only display traceback information during an APIError

Starting work on integrating fab and assy drawing generation

Additional work on fab generation

Update momo tool to lazily load modules when possible

This cuts the startup time in half and will be very important going
forward to make sure we keep the tool responsible and speedy

Working version of production file generation

Add unit test for building production files

- note: EAGLE needs brd files to be named .brd for CAM processing to work

Remove non conforming exception and update TODO docs

Update production generation to zip up result

Fix libedit logic to only apply on mac os x and not on Windows too

Start autofinding EAGLE on various OS

Add eagle autofind on mac os x in standard location

Update version number

Update modtool to show progress bars
