v1.3.0

Develop- Allow State variable set check_init=False to skip
initialization test. One use case is for integrators
with non-zero inputs (such as state-of-charge integration).

• Solves power flow for systems with multiple areas, each with
  one Slack generator.
• Added Jumper for connecting two buses with zero impedance.
• REGCA1 and synchronous generators can take power ratio
  parameters gammap and gammaq.
• New models: IEESGO and IEEET1, EXAC4.
• Refactored exciters, turbine governors, and renewable models
  into modules.

v1.0.1

• Patched the WECC dynamic data to eliminate out-of-limit initialization of ESDC2A model.
• Patched the equation update routines to generate one anonymous function for f and g, respectively, and return in a tuple.

v1.0.0

This release contains minor patches on v0.9.5.

v0.9.3

This version contains bug fixes and performance tweaks.

• Fixed an AntiWindup issue that causes variables to stuck at limits.
• Allow TDS.run() to resume from a stopped simulation and run to the new
  end time in TDS.config.tf.
• Improved TDS data dump speed by not constructing DataFrame by default.
• Added tests for kundur_full.xlsx and kundur_aw.xlsx to ensure
  results are the same as known values.
• Other bug fixes.
