fixed upload_doc.sh and added release directions to developers.txt
added elements and elementFractions
Merge branch 'elements' into develop
Incorporating the addition of elements for scdevicesim
change Ternary.elementFraction from classmethod to classinstancemethod
implemented about a third of the quaternaries, and added some examples
implemented another third of the quaternaries, and added __eq__, __str__, and __repr__
refactored and then finished implementing the remaining quaternaries
Merge branch 'quaternary' into develop

Quaternaires are now fully implemented. This closes #14.
moved examples into the openbandparams package, and updated setup.py
added strained binaries example, and added casts to float in Binary methods
small change to strain calculation
added a comment about strain calculations
added another quaternary example, and small chnages to other examples
implemented __all__, so that 'from openbandparams import *' works, and updated the examples correspondingly
A lot of changes. See full description.
* Added tests package, updated setup.py, and started writing unit tests
* Added comment about strain calculations to the strained binaries
* example
* Renamed examples with more descriptive names
* Implemented __str__, __repr__, and __eq__ in the Binary and Ternary
* classes
** This required some refactoring of Ternary, and removal of the
reversed ternaries. I'll have to reimplement the reversed ternaires
later.
* Changed Ternary to use `binaries[0]` and `binaries[1]` instead of
* `binary1` and `binary2`, and removed `binary1` and `binary2`
fixed bugs introduced into examples by the last commit
refactoring, and making Quaternary more consistent with Binary and Ternary (e.g. implementing LaTeX)
refactoring Quaternary3, adding quaternary tests, formatting
formatting code and organizing imports
fix test errors caused by last commit
