Version 0.7.0

[chrislupp]

Features

• Created a general implementation of the implicit discipline client for
  OpenMDAO. The client creates an OpenMDAO ImplicitComponent which can
  be added to any OpenMDAO model.
• Created an interface to host OpenMDAO groups in ExplicitServers.
• Added integration tests for OpenMDAO implicit components using the quadratic example
• Added unit tests for OpenMDAO linearize, solve_nonlinear, and apply_nonlinear functions
• Updated Philote protocol to version 0.7.0
• Moved tests out of the package structure
• Improved test coverage (100% lines covered by unit and integration tests, excluding generated files)

Bug Fixes

• Added a check if OpenMDAO is installed before defining any classes that use
  OpenMDAO types. This is a bug that has never (to my knowledge) been
  encountered, but could force non-OpenMDAO users to install the package, even
  though they have no use for it.
• Fixed grpcio-tools build dependency issue. Under certain circumstances (e.g., use of an older grpcio package), the
  installation will fail due to an incompatible grpcio-tools version getting installed at build time. The grpcio-tools
  version has been fixed for the build at 1.59. As a result the grpcio version also must at least be 1.59

Documentation & Infrastructure

• Updated copyright statements across the codebase
